MCINTOSH MC 225 STEREO TUBE AMPLIFIER
This auction is for one of my Mcintosh 225 has been electronic refurbished with replacement parts. The power supply capacitors and regulator diode replaced. Signal capacitors replaced; bias circuit replaced with new standard. Input potentiometer replaced. All the resistors were checked for value and out of spec was replaced with carbon resistor to retain the proper warm sounds. Keep in mind that replacing only the power supply can capacitors is not enough, those old diodes need to be replaced. Bumble bee capacitors in the signal path leaks and cause the sound to be muddy and need to replace also. After all the parts are replaced, you will have a clean clear sounding amp. Surf on the web to see what an original stock amp looks like inside and you can see what was done to this one. Tubes are made by Electro-Harmonix 7591 output tubes and small signal tubes and are new. The 12BH7 are US made. The chassis has been replaced with new manufacture unit. Unit sounds great and meet Mcintosh specs. I am a retired electronic engineer. I do restore myself. The MC225 was said to be the best sounding McIntosh tube amplifier ever made. While not as powerful as other Mc offering, there is enough punch to deliver warm McIntosh sound. The reason I am selling this is I need room for other collection. I still have one in my collection to enjoy. Power is 25 watts per channel into 4/8/16 ohms load in stereo. 50 watts mono if bridged. Frequency response is 18hz to 30khz. Total harmonic distortion is 0.5%. All sale is final, I ship to 48 US states only. Local pickup welcome. Tubes will be ship in a different box. Payment due within 2 days of close.

McIntosh MC225 amplifier restoration cap repair service rebuild kit capacitor
The scarcity of good, honest techs who can do good and reasonably priced restoration/rebuild of audio equipment inspired me to create this restoration kit. In today’s day and age, it is difficult to find a knowledgeable technician who can service your audio gear properly. I have seen many poor quality restorations of equipment that cost way too much for their owners. In 99% of the cases, only a few parts were replaced, instead of a full and proper restoration job.A proper restoration must replace all electrolytic, paper, film, oil capacitors. Do not fall for partial kits. This is not a good or proper way to restore your audio equipment. It is the same as with car tires; one should never replace just one tire and keep the other worn-out tires on. A proper rebuild requires a full recap of all PCBs.On the other hand, if one succeeds in finding a good tech, the wait time is usually 6-12 months for the unit to be serviced, and costs are sky-high. I have been servicing audio equipment for many years and have developed deep respect for all good equipment. Knowing how amazing and warm these units can sound, I decided to put together this kit. It includes very good upgrades and improvements that must be done to the unit. This restoration kit will make a huge difference in the sound quality. All the parts are of high-quality Japanese Nichicon / Rubycon / IC / United Chemi capacitors.I am extremely particular about the quality of the parts provided in this kit. Knowing how many bogus/fake caps, diodes, resistors, etc. are out there, I source all the parts from reputable wholesalers and buy them in bulk. Vintage audio equipment has the potential to deliver rich and authentic sound when it is properly restored. Not only can it enhance your listening experience, but it can also evoke memories and bring joy to your life. Let’s work together to bring your vintage gear back to its full potential, and make sure you have the music you deserve. ♩♬♫♪♫♩♬ “They Shall Have Music”- Avery FisherIncluded in this kit: 1.
