Up for sale here is this complete rebuild kit for the Sansui 8080 (or 890). This includes all the parts you need to rebuild a Sansui 8080 or 890, and includes the correct size replacement main filter capacitor. This does not include the driver or output transistors. The correct replacement outputs are the OnSemi MJ21196G, which I have available here if you need them, though if your receiver is working you don’t need to replace the outputs. Each channel uses 4 outputs, and you should replace all 4 on the channel if you are replacing any. Please don’t buy any of the Chinese output transistors on eBay–those are counterfeit and will blow up. I also have a complete light kit available here. This kit includes replacements for all the electrolytic and tantalum capacitors in the receiver, including the two main filter capacitors, which are upgraded to new 10000 uf 80v Chemi-Con caps. The new caps are the same diameter as the old ones so they will fit the old clamps perfectly. The kit also includes replacements for almost all the transistors on all the boards, except the amp driver & bias transistors and the tuner board transistors. The kit for the power supply includes a replacement dual diode and includes two fuses and four fuseholder clips to perform the recommended service bulletin. There are replacements for all of the driver board fuse resistors, and there are also replacements for the fuse resistors on the other boards as well. There is a new relay for the protection board. You will also receive detailed instructions to help this rebuild go more smoothly. These are all high-quality brand new genuine parts. These are the same parts I use when I rebuild Sansui equipment. I have rebuilt quite a few 9090s (and 5050s, 6060s, 7070s, 9090DBs, etc) in the last few years. These are amazing receivers, and they deserve a high-quality rebuild. Capacitors are Nichicon PW, Nichicon KL, Nichicon EP bipolar, Panasonic FC, Wima film, Panasonic film, and Chemi-Con for the main filters. Transistors are Fairchild/Onsemi. Why buy this kit over the others on eBay? Brand new, correct size main filter capacitors2.2 uf 250v Panasonic film bypass caps for the main filter capsA full recap kit for the tuner board–no skipping that one!The proper MY4 relay included. Otherwise, eventually the original relay will wear out, and you will lose a channel at low volume.Replacements for ALL small transistors (except the bias/drivers and tuner board transistors). There are a lot of bad transistors on the 8080, and they desperately need replacing. No one else is as obsessed with replacing transistors as I am, and no one else includes replacements for as many transistors. Your receiver will sound so much better with those ancient transistors gone.Full rebuild kit for the driver board, which includes replacements for the 4 trimmers, 12 resistors, 8 transistors, 2 zener diodes, and the 6 glass bead diodes.Replacements for the small fuse resistors on the watt meter boards.The proper low-leakage caps are included. There are loads of Nichicon KL and Wima film caps in this kit, which are necessary for a correct rebuild.8 new TO-3 mica insulators are included for the output transistorsVery clear instructions on how to set the driver board voltages8 replacement fuses for the power supply board and driver board (for the service bulletins)Surprisingly detailed and well-written instructions, plus a link to download a free service manual The Sansui 8080 has a LOT more parts in it than a typical vintage stereo receiver. This kit includes a total of 161 parts. This will be a moderately long rebuild. The parts for each board are individually bagged for ease of installation, and the instructions will tell you how the transistors and diodes go in, but there are a LOT of parts to replace here, so if you do not have a lot of experience with vintage gear I would not recommend starting with this one. You should know what you’re doing and have a good soldering iron, a desoldering gun such as a Hakko FR-301, heat-sink compound, and a dim-bulb tester with 100W or 150W incandescent bulb. Please see my pictures for details. No generic pictures here–I have clear pictures of the actual parts you will receive. US shipping and handling is $10, and international is $28. If you have any questions, please ask. Looking for more parts? I have power switches, feet, pushbuttons, top case screws, bottom screws, faceplate screws, white LED fuse lamps, blue LED fuse lamps, 6.3v bi-pin bulbs, 8v bi-pin bulbs, 12v bi-pin bulbs, wired 8v 60ma bulbs, new power cords, new main capacitors for the Marantz 1060/2230, wired Pioneer speaker plug replacements, new 630v yellow film capacitors at 38 different values, new 1200v yellow film capacitors at 15 values, a large variety of transistors for vintage stereo repair, new Wima film capacitors for stereo repair, new 250v yellow film crossover capacitors, and more. Just use “add to cart” on everything you want and then check out for combined shipping.
