Between TP5 and TP6 is the HPF PCB so check that along with the 5-pin header and the mini toggle switch as signal passes thru it.Hey! Done building 1 VP28, im getting sound and all the buttons are working functionally, LEDs working, phantom working etc.
have some test results. But the signal is very weak, measuring somewhere -70 to -30 db on my audio interface, with a sm57 and fader and pre gain all the way max. Testpoints 1-5 seem to measure values that are good. but 6-7 not really anything there.
Hope someone could help! Thanks.
