Gieger Board Troubleshooting
Posted: Tue Mar 23, 2021 5:22 pm
Not hearing anything after powering on the board.
I went through the troubleshooting and I do get the speaker and led to respond when grounding TP1, but nothing when shorting J1 and J2.
A pack of new IN4148s and TLC555CPs are on the way, but are there any other suggestions? See below for picture of the board. Note that the J1 and J2 wires are connected to the tube (not shown in the picture). I verified the contacts to the tube and don't think this is the issue since shorting J1 and J2 doesn't produce anything.
