Hi everybody. Today I received all missing parts (takman resistors for buffer, mundorf caps and transformer) and put together DCB-1. everything went well and when I started all LEDs are lit and measurements have shown these
Voltages are -10.12 & 9.95
Offsets -1.7 & -2.1
Is it ok that both offsets are negative?

Which pot are you using? I tried to find a good 20k motorized alps pot, but no luck. I ordered a 20k "blue velvet" pot from alps, but in the end I want to use my controller to control volume and inputs, so a motorized pot or a digital controlled volume control IC is very much desired.

@Marra

Are these the spacers you are running on yours? These are M3 size from the URL you posted... I'll look for similar M3 from a USA source.
