Description: Up for sale here is this P700 amplifier board rebuild set for the Marantz 2330B. This is all the parts you need to rebuild an entire Marantz 2330B P700 amplifier board. Over time the amp boards start developing issues with transistors and capacitors, and sometimes completely blow up. The old parts are weak and failing. We will make them new again! This kit includes all 10 capacitors, all 24 transistors, all 26 diodes (2 zener), and two small pieces of heat-shrink tubing. It does not include any resistors or any output transistors. I have new OnSemi MJ21195G/MJ21196G outputs listed here if you need them. The amp board uses 8 (4 pairs, two pairs per channel), and you should replace them at least in pairs if you are replacing any. Please don't buy any of the Chinese output transistors on eBay--those are counterfeit and will blow up. If your board has any burnt resistors on it, you will need to replace those as well. If they are too badly burned to read, you can use the manual (available free online) and the board markings to determine which resistor is which. It's always a good idea to test the big white emitter resistors as well just to make sure none of those blew up. These are all high-quality brand new genuine parts. The capacitors are Nichicon PW and Nichicon KL caps at the correct uf and improved voltage ratings and the transistors and diodes are Fairchild/Onsemi and are the correct subs for the original transistors/diodes. There are two matched pairs of KSC1845 transistors to replace the matched pairs on each channel, then use a little bit of heat-sink compound (not included) and the included heat-shrink tubing to pair them up. These are extremely high-quality parts, and they are what I use when I rebuild Marantz gear. Also, 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 a surprisingly well-written instruction sheet, 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.
