Pass Zen 4 project

Hi,
I have a pass z4 project that I’m never going to get around to fixing. I just don’t have the proper equipment to troubleshoot, nor the background. The left channel seems to burn a resistor. I’ve replaced it a couple of times and it works for a while then goes out. I bought a full stereo replacement prebuilt boards which I assume are plug and play. I also have extra transistors. Anyway, I’m never going to get around to installing the new boards.
The amp sounds great when it works and I’d like to to go to another hobbyist.
I’ve never sold anything here but figured this is the place for something like the Z4 before eBay. I figure $200 is a good price considering the chassis and power supply caps. (Shipping extra, local pickup available, I’m in Brooklyn NY). I think the new boards were $80.
Please let me know if I’m following the correct protocol and feel free to message me with any other questions, that hopefully I can answer.
-Haig
