Technics SU-7700 Integrated Deluxe Upgrade Kit Genuine Parts Restoration

Description: USA sourced - Mouser, Digikey, TTI, etc. Electrolytic caps are audio quality Nichicon & Panasonic caps. Very large filtering caps are the only occasional exception to that rule, but those will also be from known established manufactures - NO knock off caps...PERIOD!Deluxe and Ultimate kit Signal path caps 4.7uf or smaller will be replaced by WIMA film caps. This is a major upgrade in sonics.Transistors are almost always ON-SEMI. No inferior NEC or no name Chinese knock-off transistors. PERIOD!Relays, trimmers and other associated parts are also sourced using the highest standards. Brands include Omron, Bourns, Radwell, etc. PriceWe strive to offer pricing that makes sense. Our kits offer superior parts AND lower prices than our competitors*Priced low by buying in bulk, NOT by cutting corners on quality. As of late 2021, With current supply chain problems, we have seen recent increases in prices on electronic parts and a decrease in availability. Those same supply chain problems make sourcing all parts needed for a restoration almost impossible via one distributor like Mouser or Digikey, this kit will save hours of time, much hassle and shipping costs from multiple suppliers. *EXAMPLE: (Jan 2022) Pioneer SX-650 Ultimate Kit = $109.95 $5.00 ShippingEbay Competitor #1 = $119.95 *No tuner parts $8.00 shippingEbay Competitor #2 = $165.00 *No Wima film caps, includes fuses $10.00 shipping Mouser/Digikey = $93.82 *Must compile (or find) a parts list first. Currently out of stock of KSC1845 transistor (expected 06/22) & other parts. No documentation, Not sorted, No support. DocumentationEvery kit includes a parts list that includes their board and board locations. Parts are separated by board. A PDF of the service manual is includedInstruction and Hint Sheet. We have compiled an extensive yet easy to read instruction and hint sheet. Written for the novice it also includes some "hints" and "tricks" even the experienced have found useful. BackgroundWe have been lovers of all things hi-fi for a very long time. We have repaired and restored 100's of units over the years. Kits and documentation take advantage of our experience as well as the cumulative experience of others in this hobby. While we can’t walk anyone through a full restoration, we do gladly offer help for those who need it. Run into a problem? If it’s not in the documentation provided, send us a message or email. Disclaimers:Pictures are for reference only. With well over 200 units listed, the options above for each unit and changing stock due to part availability, the picture may or may not be accurate for your unit. Rest assured the kit will be. This is a challenge of marketing, sourcing and time, not quality. As of late 2021, supply chain problems are real. We have bought in bulk for standard caps, transistors etc. but occasionally a high volume of orders may lead to absent stock. It's rare, but occasionally we will have to ship a particular part out separately. If so, we will do so ASAP and notify you when you place your order. In almost all cases any tardy parts will ship to you within a week. Service Manual and/or packing errors do happen. Again, this is rare but it happens. Simply contact us with any missing/mistaken parts and we will ship them to you free and fast. If you are unhappy with the kit for any reason, simply return it for a full refund. Change your mind, return it. Your spouse sold the unit while you were sleeping, return it. Having sold well over 500 of these kits in our first year of doing so, we don't worry about the rare return. If ordering a deluxe or ultimate kit, only DC offset, Bias and Power supply voltage adjustment trimmers are included. Tuning and other less critical tuners are NOT included. Standard kits do NOT include any trimmers.If you do not receive the PDF documents via email before the kit arrives, contact us when it does. We strive to send these out the day we ship your kit but things can get busy. The pdf docs are sent to the email address associated with your Ebay account. PLEASE - after purchase if you need to correspond do it via email if possible. The Ebay messaging system can be cumbersome. Thanks!I hope we didn't forget anything here. We work with customers and value our reputation. Our hope is that you have a clear understanding of what to expect and once you receive it, it meets that understanding. This listing is an attempt to be clear and concise without writing a novel. If you have any questions not covered here send us a message. ShippingCustomers located in the USA will have their kit shipped via USPS with tracking. In almost all cases kits ship within one business day of purchase. If you live outside the USA, kits are shipped via the EBAY international shipping program. If you are reading this and shipping to your location is NOT an option - simply contact us. Ebay Stuff:Please don’t leave negative or neutral feedback. If anything seems amiss, contact us. As mentioned above, the Ebay messaging system is cumbersome. If you ask a question and get no reply, feel free to give us a nudge with another message. We offer help to buyers of kits and therefore get a lot of messages. Again, email is always preferred.________More Details____ Quality PartsAll signal path caps 4.7uf or lower are replaced by sonically superior film caps, most by WimaAll transistors are made by OnSemiElectrolytic caps are primarily Nichicon.
