Marantz SD340 Cassette Deck Ultimate Upgrade Kit Genuine Parts Restoration
Superior to other kit suppliers (Wima film caps sound better, transistors replacing known problematic one's) our kit will bring out the best in your deck! And as of this listing less expensive too! Whether a cassette deck or reel deck, the sonic improvement of a quality recap (especially with the Wima film caps) will likely shock you. 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 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. Please note as the years went by manufactures stopped using the problematic transistors. Therefore units made after roughly 1985 (often earlier) will not have problematic transistors. We evaluate all units upon compiling the kits, no matter the manufacture date but many more "modern" deck kits will not have transistors included. 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 an extensive instruction/guidance sheet with some helpful hints. It is not a step by step guide for individual units. But, with it, the service manual, our part number labeled parts list you will have everything you need to get the job done. This kit is for electronic parts only. No belts or other mechanical parts are included. 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.
