Just put together the EZ1073-500 kit however the max bias I can get with the trim pot is 24mV (should be 90mV) and the relay is not clicking in.
With the vertical boards it's hard to trouble shoot but from the few spots a could check it appears the proper 16 volts is reading at points I can measure.
Before I start removing boards It would be nice to narrow the problem down and pretty sure the relay not clicking in is a clue.
Also it does power a condenser mic with 48 phantom and passes signal, albeit a little crunchy. It is also quiet so no noise or hum, so I don't think completely screwed it up. Pretty sure something in the output stage is botched.

Any ideas or advice greatly appreciated.
Thanks,
Scott
