Up for sale here is this complete rebuild kit for the Marantz 1122DC amplifier. This includes all the parts you need to rebuild the Marantz 1122DC P800 power supply board, P700 amplifier board, P400 phono EQ board, PE00 tone board, PS00 switch board, and PV00 mic board, plus it includes upgraded replacement main capacitors. This does not include new fuses or output transistors.
This kit includes the following:
Power Supply Board:
9 capacitors
7 diodes (1 zener)
5 transistors
1 relay
Amplifier Board:
14 capacitors
22 transistors (including 2 matched pairs for differential transistors)
16 diodes
2 trimmers
1 piece of heat-shrink tubing (for differential transistors)
Phono EQ Board:
11 capacitors (2 extra to account for board variations)
6 transistors
Tone Board & PV00 board:
17 capacitors
8 transistors
2 new main capacitors (same diameter and mounting pin pattern as the old ones, upgraded uf rating)
2 1 uf 250v film caps (for rear speaker switch)
Instructions
The kit for each board is bagged individually to make things easier.
These are all high-quality brand new genuine parts. The main capacitors are Cornell Dubilier 15000 uf 63v caps, the other capacitors are 105° Panasonic FC, Nichicon PW, Nichicon KL, Nichicon VY, Nichicon LGU, and Wima film caps at the same or improved uf ratings and the same or higher voltage ratings, and the transistors and diodes are the correct Fairchild/Onsemi subs for the original transistors. Most of the capacitors are the same capacitance, but five go higher--the two main caps are 15000 uf 63v, the 270 uf 160v power supply cap is increased to 470 uf 160v, and the two 33 uf phono board caps are upgraded to 47 uf Nichicon Muse caps. These are extremely high-quality parts, and they are what I use when I rebuild Marantz equipment.
I will include surprisingly well-written instructions, but rebuilding an amplifier is fairly complicated, and you should know what you're doing and have a decent soldering iron, heat-sink compound, and a dim-bulb tester with a 60W or 100W incandescent bulb. Please see my pictures for details.
US shipping and handling is $10, and international is $28. If you have any questions, please ask.
