This is a Deluxe Restoration kit for the listed unit featuring Wima film caps. We also have a standard kit available.
In addition to our standard kit, this kit includes:
Wima caps: 14Trimmers: 5
Relays: 1Filter caps: 10kuf 80v Nippon Chem-Con 35mm diameter (same size as the originals)
Kits include all on board capacitors to recap/restore all amplifier sections of this receiver. Caps for the tuner section are NOT included. The kit also include...s transistors to replace those we now know are noisy or otherwise problematic. It also includes the off board filter and coupling caps if needed. It also includes bourns trimmers (for critical amp adjustments) and the relay if used. This will restore a working unit to better than showroom sound (thanks Wima!), drop the noise floor and probably make you wonder why you waited once you hear the difference. It will also remove parts that are well past their promised shelf life and whose failure could take out other parts as well. Kits are separated by board for easily locating parts as you work.
The kit replaces electrolytic and tant caps with high quality new ones sourced via reputable USA distributors like Digikey and Mouser. Most caps are Nichicon high quality UKL and UPW capacitors, we also sometimes use Panasonic FC caps for filtering in spots. All new caps will be the same capacitance as the originals with voltage ratings at least as high as the originals and oftentimes higher. Any capacitor of 4.7uf or lower is replaced with a high quality Wima film caps for better sound and reliability.
Transistors are also sourced the same way and almost all are highly reliable on-semi devices. Not all (not even most) transistors get replaced, just those that time and collective knowledge have shown to be either noisy, unreliable or at the edge of their operating ability.
Trimmers are supplied by bourns and relays (if used) are made by Omron.
The individual doing the work should be competent with a soldering gun, multimeter, reading a schematic etc. I am not a tech, but I have successfully done hundreds of restorations over the last 20 years.
Many of the parts lists for these kits were compiled when we restored units, others are sourced from the service manuals (digital download included in purchase if you don't know how to source it). We have compiled parts lists for well over 200 units for units from Marantz, Technics, Pioneer, Sansui, Harman Kardon, etc. We do not sell kits for tube gear currently.
If the service manual is wrong (it does happen) we will ship you out the correct parts free of charge. The same is true if we make a mistake in compiling the kit ( I hope not but just in case). We want this process to go smoothly for you.
Included is a two page instruction/guidance sheet with some helpful hints. It is not a step by step guide. But, with it, the service manual, our part number labeled parts list you will have everything you need to get the job done.
The primary picture is this actual unit! Parts are bagged by board
FAST shipping: The kit will ship (usually the next day) via USPS First Class with tracking.
We have bought in bulk hoping to provide the community with an easy, time and cost effective solution. Any feedback on how to do that better is appreciated.
Thank you
