Hi guys
I have an otherwise perfectly performing K2 that has inoperative CAT.
CAT was working properly over the past 2 years so something has
changed. I do not remember trying it after performing the latest
KPA100 mod and firmware upgrade so it could have crept in there, but
I have ensured that there are no cold/bridge/bad solder joints there.
In investigating, there is very little (-0.2v) on pin 8 of u4.
Following the circuit backwards, I have nowhere near normal voltages
over d1-d8. I have verified that the diodes are all okay, no bridges
or poor solder connections.
Does this sound like the oscillator at X1 is not firing? Is there a
good way to know?
