Up for sale here is this complete rebuild kit for the Marantz 3250 preamplifier. This is not for the 3250B, that one is here. This includes replacements for all electrolytic capacitors on the 3250, as well as replacements for 36 transistors (most, but not all of them).
This kit includes the following:39 capacitors (Panasonic FC, Nichicon PW, Nichicon KL, TDK film)
36 transistors (30 Onsemi, 4 Toshiba, 2 STMicro)
Instructions
These are all high-quality brand new genuine parts. The capacitors are all at the same uf ratings and the same or higher voltage ratings, and the transistors are the correct subs for the original transistors. These are extremely high-quality parts, the same ones I use when I rebuild Marantz equipment.
I will include surprisingly well-written instructions, but this is moderately complicated, and it is a little difficult to gain access to the bottom of the board--you will need to do a little disassembly work, which the instructions do not cover. You should know what you're doing and have a decent soldering iron, heat-sink compound, and a dim-bulb tester with a 40W, 60W, or 100W incandescent bulb.
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 power cords, new main capacitors for the Marantz 1060/2230, wired Pioneer speaker plug replacements, new 630v yellow film capacitors at 38 different values, new 1200v yellow film capacitors at 15 values, a large variety of transistors for vintage stereo repair, new Wima film capacitors for stereo repair, new 250v yellow film crossover capacitors, and more. Just use "add to cart" on everything you want and then check out for combined shipping.
