Up for sale here is this amplifier board rebuild set for a Pioneer SX-535. This includes all the parts you need to rebuild a Pioneer SX-535 AWH-035 amplifier board. The old parts are weak and failing. We will make them new again! A lot of SX-535s will have an aggressive crackle in one or both channels from aging transistors, and this kit will usually fix that.

This kit includes all 9 capacitors and 10 transistors for the amplifier board. This does NOT include any output transistors.  The correct replacement output transistors are two KSB596 (replaces 2SA489) and two KSD526 (replaces 2SC789), available here.

These are all high-quality brand new genuine parts. The capacitors are Wima film caps, 105° Panasonic FC, and 105° Nichicon PW caps at the same uf ratings and the same or higher voltage ratings, and the transistors are new Fairchild/OnSemi transistors, the correct subs for the original transistors. The replacements for the differential pairs are matched for HFE in order to minimize DC offset. These are extremely high-quality parts, and they are what I use when I rebuild Pioneer equipment.

I will include surprisingly well-written instructions, but rebuilding an amplifier board is at least mildly complicated, and you should know what you're doing and have a decent soldering iron and ideally a dim-bulb tester with a 60W or 100W incandescent bulb. 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, a large variety of transistors for vintage stereo repair, and more. Just use "add to cart" on everything you want and then check out for combined shipping.
