Marantz 4400 COMPLETE Rebuild Kit Recap Set with Transistors Relays (373 Parts)

Description: Up for sale here is this complete rebuild kit for the Marantz 4400. This includes all the parts you need to rebuild a Marantz 4400, and includes the correct size replacement main filter capacitors. This does not include new lights or fuses. This also does not include the driver or output transistors. I have new OnSemi MJ21195G/MJ21196G output transistors here if you need them, though if your receiver is working you don't need to replace the outputs. Each channel uses 4 outputs (2 pairs), 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 replaced with new 22000 uf 80v Cornell Dubilier caps. The new caps are the same diameter as the old ones so they will fit the old clamps perfectly. They go up a bit in capacitance and voltage, which is fine, and will improve the sound. The kit also includes replacements for almost all the transistors on all the boards. The kit for the power supply includes replacement diodes and dual diodes, and there are 1N4148s included to replace the VD1212 glass bead varistors on the boards. There are also two new relays. These are all high-quality brand new genuine parts, the same parts I use when I rebuild Marantz equipment. The 4400 was one of the best Marantz receivers, and it deserves a high-quality rebuild. Capacitors are Nichicon PW, Nichicon KL, Nichicon Muse, Panasonic FC, Wima film, Panasonic film, Supertech axial, and Cornell-Dubilier for the main filters. Transistors are Fairchild/Onsemi and 2 Multicomp. This kit includes the full power supply rebuild kit, but does not include the P900 scope board rebuild kit, which you will not need unless your scope board has bad transistors (very uncommon). Why buy this kit over the others on eBay? The FULL power supply rebuild kit, with all the high-voltage caps and diodesBrand new, correct size main filter capacitors2.2 uf 250v Panasonic film bypass caps for the main filter capsA full recap kit for the tuner boards--no skipping those!New axial caps for the amp boards.The proper relays are included. Otherwise, eventually the original relays will wear out.Replacements for almost all the small transistors. There are a lot of bad transistors on the 4400, and they do 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 2SC1345s gone.The proper KSC1815 transistors for the phono board--the KSC1845s will not always work properly here!Replacements for the glass bead varistors, which need to be replaced.8 new TO-3 mica insulators are included for the output transistors.Surprisingly detailed and well-written instructions, plus a link to download a free service manual. The Marantz 4400 has a TON of parts in it. This kit includes a total of 373 parts, so this will take a fair amount of time. 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 $15, and international is $40. 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.
