Hey guys, this is a crosspost from diyAudio, was wondering if you guys had anything to add recently have started making an o2 amp. While checking through all voltages on the board, using NwAvGuy's troubleshooting guide. I noticed that the DC offset at P2 measured 36 mV and 16 mV, which is a...

I have an old Channel Islands VHP-1 amp and when I measure its DC Offset it's very close to 0v, showing 0.0 mV on my multimeter. But when I change the volume, gain setting, or turn off the device the DC Offset can spike up to 30, 80, 175 mV respectively, then slowly make its way back down to 0mV...
