Description: Up for sale here is this P700 amplifier board rebuild set for a Marantz 4300. This is all the parts you need to rebuild ONE Marantz 4300 amplifier board. There are TWO amplifier boards in a 4300 or 4400, so if you need to rebuild both amp boards, set the quantity to 2 when you buy. Over time the amp boards start developing issues with diodes, transistors, and capacitors, and sometimes completely blow up. The old parts are weak and failing. We will make them new again! This kit is intended to rebuild a working amplifier board, though it can fix your board if you have issues with the smaller transistors. It does NOT include the larger transistors, so if you need those as well, I have a kit here that includes all the large transistors. This kit includes all 8 capacitors (replacements for all the electrolytic & tantalum capacitors), 18 diodes (replacements for all the diodes, including the zeners and the VD1212s), and 14 transistors (replacements for all the small transistors on the board). It does NOT include any resistors, the big white resistors, or any output transistors. I have new OnSemi MJ21195G/MJ21196G outputs listed here if you need them. Each amp board uses 4 (2 pairs), and you should replace all 4 if you are replacing any. Please don't buy any of the Chinese transistors on eBay--those are counterfeit and will blow up. These are all high-quality brand new genuine parts. The capacitors are Nichicon PW, Nichicon KT, and Wima film caps at the correct uf and the same or higher voltage ratings and the transistors and diodes are Fairchild/Onsemi and are the correct subs for the original transistors/diodes. These are the same parts I use when I rebuild Marantz gear. Frankly, "recapping" is a waste of time if you're not going to replace the transistors as well. A lot of times the transistors age worse than the caps, so you should definitely change out the transistors while you're in there. If you're having amp board issues, it's very likely to be a transistor issue. I will include surprisingly well-written instructions, but this is a pretty complicated repair, so if you don't have much experience with this, buy the kit and take it to a professional. You should definitely have a fair amount of soldering experience and have a decent soldering iron, a dim-bulb tester, and heat-sink compound, as well as the usual tools. Please see my pictures for details. US shipping and handling is $5, and international is $18, no matter what quantity you buy. All my small parts are set up for combined shipping, so just use the "add to cart" feature and then check out all at once, and it will combine shipping. If you have any questions, please ask. Looking for more Marantz 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 main capacitors for the 1060/2230, and more. Just use "add to cart" on everything you want and then check out for combined shipping.
