Item Category: Vintage Electronics

This kit is for early mk1 but also covers all models mk1 – mk4.This is a very basic kit for all models. I stress – very basic. It will address immediate concern items that are at high risk of burning out completely due to old age. Please also consider our other kits which may be appropriate for your project. ALL our motor capacitors are specially made for Revox and Studer tape recorders to our design specifications.This kit includes the associated paper AC suppressor capacitors that commonly give problems in the capstan speed control and tape drive control. 2x 4.3uf 250 VAC reel motors capacitors1x 3.5uf 250 VAC capstan motor capacitor5x 0.47uf 300VAC AC X2 suppression capacitors 1x 0.1uf 300VAC AC X2 suppressor capacitornow includes 4x special high voltage suppression resistors for the tape transport board which we have found are often damaged when a capacitor is faulty and was an official factory tech update.Motor caps size 30mm D x 50mm H (overall height with terminals). They fit perfectlyThis kit will fit ALL A77 mk1 – mk4. MOTOR CAPACITORS: Our precision high grade motor capacitors are specially made to our specifications for us for Revox and Studer tape decks. They are non polar foil types specially made for motors and are rated at 250 VAC. There are NOT generic white washing machine / fan capacitors which have wide specification tolerances. They are also the exact Revox capacitance values not “approximately close”. Anyone who implies that a higher capacitance value is better is talking nonsense. Other Ebay vendors have started copying us and offer copy cat kits many with inferior white washing machine capacitors and dubious non X2 rated suppression capacitors. Never use old motor caps – its just not on and is a rip-off! Dont buy dubious 2nd hand or NOS capacitors. White plastic generic washing machine or fan capacitors – they are mass produced to wide specification tolerances, inaccurate and – frankly good for fans and washing machines BUT not precision tape recorders. Especially don’t believe anyone who tells you that a different higher capacitance is better! What absolute rubbish! Everyone knows better when they have something to sell!GENERAL INFORMATION ON OUR KITSOur kits contain specially sourced, new, freshly manufactured components from reliable manufacturers whom we have been dealing with for many years. No NOS (new old stock) or 2nd hand items!! The motor capacitors are specially manufactured for us for Revox tape deck motors as are large power supply can type electrolytics. The audio signal path capacitors are specially selected low noise, low leakage / high stability types that we have specifically tested and sourced to be the most appropriate available. The preset pots are cermet fully enclosed guaranteeing decades of trouble free operation and adjustment.What About – other audio path caps and transistors – I try to design kits on teh basis of what is most likely to be degraded without going over the top. We don’t usually supply audio path related non polarised path paper, mica, poly or other caps satchel. They are trackable and take 4-10 days to most of Australia except the wop wops which is a bit longer. International. Tracked or registered Airmail International via Australia Post International Airmail Service. To those countries postal service that have a transparent international tracking system – we will send via a special Australia Post tracked service (Pack n Track). For those countries who don’t have an international compatible trackable collaboration we will send registered post which is safer, is not user trackable but is trackable until it enters your country but once it there. The cost is typically approximately ~$20 to New Zealand and parts of Asia, ~$26 to N America and other parts of Asia and ~$30 to Europe and most other parts of the world. The Ebay calculator will work this out more precisely and WILL include their commission!! Time to destination. 1 – 4 weeks. Mostly the speed is outstanding but sometimes it’s a bit slow for an airmail service but I think things get held up in your customs and local post who take their time. Please see proviso above of your risk if only registered or airmail service to your country is selected or only available. Want your stuff in a hurry? Courier / Express International. This is a fast (2 – 4 days), trackable, insured service and “ouch” expensive. We use either Australia Post EMS or DHL. Is it worth It.? If you are in a hurry or are really dubious of your post system (eg most places in Africa) then maybe. We are investigating a DHL service that gets out of Australia on DHL but then coordinates with the national postal service in your country. It’s looking promising… From time to time I may coordinate multiple items postage to a particular country and you may get your parcel via your local postal service. Please don’t ask me to specifically use this facility as I may not be able to. All postage out of EEC will be using La Poste or Royal Mail and the “signed for” option which is trackable.DECLARATION of value. Usually this is at what you paid. However, I believe, vintage audio enthusiasts should not be penalised for their hobby by greedy governments! So, if you want a specific value declared but at your risk, just ask. Usually AUS$25 is the threshold.POSTAGE WEIGHT CATEGORIES The first tier of weight category is at 500g and then 1Kg, 1.5Kg etc. (Domestic next category is 3Kg). If it goes over 500g for international its roughly 0.85x the lesser weight category cost. Most cap pot kits weigh between 245 and 450g. Motor kits are about 150g. Do ask for postage consolidation / invoice otherwise Ebay calculates separate postage charges on multiple items and it will cost you more. WE DEFINITELY OFFER COMBINED POSTAGE.3. YOUR ADDRESS – this is really really importantIt may be obvious but PLEASE make sure your address is 100% correct and add more information if there could be any possibility of ambiguity. THERE IS A LIMIT of 32 characters per line in the ebay / Paypal / Australia Post automatic link up and it does not warn you that address lines longer than 32 characters will be truncated. Do not exceed this 30character including spaces limit per line. Do not use foreign language symbols like o ß ˘ ˆ – ~ ° Ç . The automatic link between Ebay / Paypal and Australia Post will not translate these correctly and your parcel may be incorrectly addressed. We rely on this auto link up which is very good but won’t translate symbols properly or long lines of characters. Please also use capitalisation for your name etc. It’s very unprofessional and just sloppy to use all lower case – yes I am a grumpy old man!. You be surprised how may addresses we get from Ebay without capitalisation, vague inferences to house or flat nos, all long address on 1 line and incomplete names. The information you provide to Paypal is automatically transferred into Australia Post and onto a label. IT MUST BE PERFECTLY CLEAR and ACCURATE. If it isn’t – the fault is with you and so is the risk.Please make sure: · DON’T exceed 30 characters per line including spaces. Use an extra line. · Your full name is clear and capitalised appropriately eg Mr Firstname Surname etc· House / flat / section number and street number are clearly demarcated with a comma and space between them. Don’t use foreign language symbols like o ß ˘ ˆ – ~ ° these won’t be directly translatable by Aus Post / Ebay / Paypal. Spell it out on a separate line if it is a flat in a block in a street – no shorthand.· Suburb, Town is clearly shown · City is shown on a separate line· UK people – Australia Post does not recognise your little hamlet of 5 people in the middle of a suburb or town. Add more information in case it spits the dummy which it often does for UK addresses – it likes a known suburb, town or city. · Postal or Zip code is shown exactly as it should be. Don’t add spaces, embellishments or abbreviations. Australia Post system checks to see it is a valid international post code and spits the dummy if it isn’t. · DON’T use abbreviations for your state. Spell it out fully. Australia Post / ebay link up has a problem with this. Eg TX, MN etc means nothing to it.· Put your phone number in. SERIOUSLY its good idea if your post service want to get hold of you concerning your parcel! So many people don’t put a phone number in – why?· Put your direct contactable email address in – and please not one that you never use – I am not psychic!4. WAITING FOR YOUR PARCELWe only post out once a week usually on a Friday or if the wheels wobble, on Monday. We have given approx transit times above and these are on the pessimistic side of what Australia Post indicates. Usually things are sent within a day or two airmail out of Australia once lodged. However parcels are often held up with your local post and customs for days and even weeks. From time to time we will also post out some parts from the EU using either LA Poste or Royal Mail this may or may or may not speed things up – who knows! Parcels to South America and East European countries can take up to 6 weeks – why – only the Gods know! Canada often has very slow postage. UK, EU and USA are usually pretty quick but there are exceptions sometimes to the USA where some states postal service sometimes forget to wake up in the mornings. 5. GETTING SERVICE SHEETS and LITERATURETHESE ARE NOT INCLUDED IN WHAT WE SEND YOU – you must request them. We do not include these in the parcel simply because postage and printing will cost more and updates are difficult to accommodate. So, once you have received the parcel please contact us on our direct email (no ebay mail please!) and indicate what kit you purchased. Contact us as per package label and we will gladly authorise MailBigFile to send you a once only link to download the service sheet. Please no Ebay mail – we cannot use that service for service sheets – it’s JUST NOT POSSIBLE. Remember, please also detail exactly what kits you purchased as it saves me time having to look it up. The service sheets are too big to send on normal emails as some email providers have a limit of 10 Mb. Some of our files are 200Mb. So MailBigFile works well. Please just be patient during the down load – it does take time and the strange interface makes it seem like nothing is happening. It is … go make a cup of tea! Please note ALL our literature is copyright and by receiving these you implicitly agree to comply with our copyright policy.6. SUPPORT FOR NAGRAVOX KITS and PARTS.I supply service sheets and support on the following basis.You must request the service sheets by communicating directly with me by email after your kit has arrived as per above. This then will be sent via a download service as a pdf document as they are usually too big for email. This may seem a strange way to do things but it is the most effective for me to make sure you have the latest service sheets as well as minimising postage and printing costs. Parts and cut down kits don’t generally have service sheets – only full kits. Sometimes however I may have written a technical note applicable to a particular part and its installation which with pleasure is available to you.Personal online support in the form of questions, problems, issues, advice etc via email or Skype or Facetime can only be given to those diy purchasers that have purchased kits and downloaded the applicable service sheets. Please don’t expect support if you don’t bother to look at my service sheets. Although I have never had to limit the amount of time I give you in free support, in the future I reserve the right to possibly ask you for payment of extended support that may run into many hours or over many days.Service Sheets are strictly copyright protected and I reserve all rights in any form of my IP.

IMPERFECTIONS definitely NO NOS or 2nd hand!WE DON’T SELL ANY 2nd HAND CAPS or POTS! On the can type multi-caps and electrolytics we hand make these and epoxy encapsulate them so there may be small traces of glue on the terminals. Just scrape or file clean before soldering. Gosh … it is hand made by me personally… I might even autograph one for you…. and may be famous one day …8. IF YOU HAVE AN ISSUEPlease contact me by simply sending a message on ebay or directly (better). Any other response somehow invokes Ebay police! This includes “I haven’t got my package yet”. Ebay very unfairly immediately consider the seller guilty of something and block funds with a pending black mark. Even if you have only just asked! We have very few issues and pride ourselves that nearly all are resolved easily. Very seldom do we have an unreasonable customer and most of you are into the spirit and credo in which I make these kits and parts available – indeed my raison d’etre. I am here not because I need to make a living from Ebay as a beady eyed vendor or want to gouge as much as I can out of you. I am here because I want to see more of these old machines restored and treasured as they should be. If you are grumpy and a pain in the …. with an attitude please rather don’t buy anything from me. If you are a happy sort and have a positive outlook seeing the good in people rather than the negative, you will get a lot out of me and our relationship. We should always be able to sit down and have a cup of tea, glass of wine and a chat. So – No boneheads please! Thanks. Remember, contact me direct which is easier for me to give in depth answers. I apologise for all this “official” stuff above but over the years it has become necessary unfortunately. Good on ya (as we say down under!) for reading this far! All the best with your restoration and hobby. I hope our kits and parts can help you achieve your goal of a perfectly operating Studer or Revox machine … running like the proverbial Swiss watch! May the analogue force be with you. Kind Regards,
