Description: Up for sale here is this P700 amplifier board rebuild set for the Marantz 2250 or 2250B. This is all the parts you need to rebuild both Marantz 2250/2250B amplifier boards. 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 set of working amplifier boards, though it can fix your boards if you have issues with the smaller transistors. This kit includes all 10 capacitors (replacements for all the electrolytic & tantalum capacitors, 4 transistors (replacements for H702-H703), and 4 diodes (replacements for the MV-13 varistors). It does NOT include any other diodes, the other transistors, any resistors, or any output transistors. I have new OnSemi MJ21195G/MJ21196G outputs listed here if you need them. Please don't buy any of the fake Chinese "Sanken" 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 KL, and Wima film caps at the correct uf and the same or higher voltage ratings and the transistors & diodes are Fairchild/Onsemi and are the correct subs for the original transistors/diodes. These are extremely high-quality parts, the same ones 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 moderately 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 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 Marantz 1060/2230, wired Pioneer speaker plug replacements, new 630v yellow film capacitors at 13 different values, and more. Just use "add to cart" on everything you want and then check out for combined shipping.
