While things are removed do resistant tests. That will fix 95% of them.

Yes, it's getting 24V out of the transformer now. I also scoped Pin 6 on IC303 (East West IC) and it has the indicated 20.5V supply. In fact, all of the Pins around IC303 look hunky dory except Pin 7, which is suppose to be the parabola.

I changed all the caps on the DA board already because they were the early surface mount kind and were all dead. So unfortunately I can't do resistance tests with them out of circuit.

I've got a new East West IC coming on monday, so I'll try my luck with that and cross my fingers. Otherwise, I might have to remove the caps and start looking for an open resistor or something.
