So just reflowed everything and gave another check to all the joints, and to make sure there are no shorts on lead ends etc. I also pushed the op tx connector all the way down finally. Still get no relay click, and while the sound is better through the unit it is still a bit quiet and crunchy, which I would assume would be sorted with proper biasing.

the worrying thing is that there is no relay click and the voltage between TP1 and TP2 is the full 16VDC. This has to symptomatic of the root of the problem.
Anyone have any ideas why the relay wouldn’t be clicking?
