I just realised that I had the impedance pot attached across #10K instead of RLoad. Doh! :lol: I've fixed that now and retested voltages again. Most voltages are ok except: #BD681 : 43.5v Bottom Right 470uF : 44.3v (looking from above) Bottom Left 470uF : 21.8v XFMR Yellow : 21.8v XFMR Blue : 21.8v ...

Phantom power on is when the 48v toggle is switched away from the PCB. Does the 48v led turn on? When you turn the power switch on do you hear the relay click on the FET DI? If not check you have the diode on the DI the correct way around. The phantom power led is not working. I can hear the relay ...

Hi Joe, I’ve just built my first BA and am having a few issues with it, hoping someone here can help me out. I am getting signal through to my DIGI 002 line input, however the signal is extremely low. (BTW this is my first DIY project so apologies in advance if I’ve done something stoopid!) :oops: H...
