These are all high-quality brand new genuine parts, the same parts I use when I rebuild Marantz equipment. The 4300 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.
Why buy this kit over the others on eBay?
- Brand new, correct size main filter capacitors
- 2.2 uf 250v Panasonic film bypass caps for the main filter caps
- A 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 4300, 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 4300 has a TON of parts in it. This kit includes a total of 345 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.
