Hi guys,
So one of my M Boards (°4 on CH I) goes silent after a warm up. I have established that the tuning goes down to the point that it's not auditable. The problems that it is almost Impossible to trace because when I take it out for inspection it cools down and sounds ok again (in tune! ).
Here is what I did so far:
1. Cleaned VCO's legs and applied fresh heat conducting agent between the IC and the diode.
2. I have bought that I have the same issue as MFox (described here ?so I have changed the IC3. Dod not work.
As I sad the problem is diagnostics. Did anyone have a similar problem?
