Hi, I recently acquired two 5370B counters with bad input channels. One has a bad start channel, the other a bad stop channel. I have traced the problem to the input board A3, which is the board directly behind the BNC connectors on the front panel.
Has anyone had any luck repairing the input circuitry in these units? Is there a common failure mode that occurs when signal levels are exceeded? Thanks in advance.
