Hello,
I am new to fixing electronics by working on the PCB and I have very little soldering experience but I will probably manage with most of the bigger connections on the board I’m trying to fix.
The problem is the DAC board which uses a 6922 tube. When the T1 is powered on all it does is produce an audible buzzing sound, the tube never warms up. I know that the tube, the amp board and the power supply work because I have another T1 on which I've tested them.
On a visual inspection the board with the problem looks, as far as I can tell, just fine with no evident burns, blown up components or bulging capacitors.
Unfortunately I don’t have any schematics but I do have some stock pictures of the board which are probably more detailed then what I could get right now with mine.

I have or I’ve ordered most of what I will need to test most components but if someone with more experience knows the obvious problem or the most likely problem I would appreciate the information.
