You probably have read the documentation, as in hificollective ?
pin 1 is input, pin 2 out, C (or 3) GND...
(I don't know about which is 1 or 3, would adhere to the standard, like for the Alps…)
If this is/was not the problem, I'm out of context…

A year later I caught up on DCG3. First power on everything clear, nothing suspicious, measurements ok. After 15mins and VR1 adjustment 0 DC offset without and with the opamp. Temperature inside the heat sink (about 40 minutes powered on is 43C), in open space as in the photo. First impression regarding sound, I could not thank you more!
Thanks cyberpup, will do (although I cannot detect any hum with the headphones). This is a temporary connection, to test things. Among others, I have to tidy up cabling a bit, raise the volume pot to fit in the face plate and complete the remote control and VU meters connections. I am concerned a little about the temperature though, maybe I will have to resort to a larger sink.
Yes at a speaker power output. Fingers crossed it is still working fine
