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
Better not borrow from your DCSTB 17.6V regulated output. Not to mix a potentially interference prone line.
At DCSTB 2200uF C2's pins you will find +V/0V raw DC points to tap. Will almost certainly measure higher than 24V given your mains & transformers.
Put a 10k resistor in series with the switch's red or black thinner wire feed to its LED so to protect it.
Or a 20k trimmer wired like a rheostat (adjustable series resistor) to can control your preferred brightness. Start from midpoint trimmer setting before power on.
