Easy to install, this kit replaces all electrolytic capacitors. Bad capacitors are a primary cause of problems.
Includes digital access to both the service and owner's manual.
The kit replaces electrolytic and tant caps with high quality new ones sourced via reputable USA distributors like Digikey and Mouser. Caps are Nichicon high quality UKL and UPW capacitors, 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
- 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 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

HIghest Quality
No Counterfeit Parts
Ultimate Kits include the following*
Replacement Caps for every electrolytic or tantalum cap in the unit, including tuner sections
Unless otherwise noted, this includes any off board capacitors including the Filter and Coupling Caps
Off Board caps may be smaller in diameter than the originals, our documentation provide a few easy options for installing these
Replacement Trimmers for critical audio adjustments like bias and dc offset (where applicable in amplifiers and receivers). Other Kit supplier do not include these.
Replacement Relay where applicable
*Not all units use a relay, not all vintage relays have a modern replacement, and finally not all vintage relays can be ascertained from available data
Kits are priced accordingly, you can view our parts list to see if your kit includes the relay(s).
Replacement Transistors and diodes for those we now know were problematic
*Not all transistors and diodes are replaced, nor should they be.
Our Parts List shows all the transistors and diodes included
Many units made after around 1982 have few or none of these problematic transistors
