I don't like my first post on this forum to be a "Help" post but here it is; I just finished building a VTA ST70 including a TDR, and the first thing I did was test the TDR board. The red LED turns on when I turn on the amp and after ~17 seconds it goes out and the green LED turns on. Looks good so far, but when I check there is no voltage on pins 4 & 6 on V1. When I did this check again I noticed that even though the green LED turned on I did not hear a click from the relay. I double checked the component and wiring installation and it seems ok but the relay is not activating. What should I check to fix this?
Nothing like having a new amp and I can't play any music.
