Finally got a C4!
Working, sounds great straight away.
However doing the adjustments, and even after installing Bourns trimpots, the DC on both channels ranges from approx 10mV to 350mV. Very steady rise and fall over the course of a minute or two.
DC is rock steady at 35.2V
Question:
Is there a ‘most likely’ first suspect?
Was going to spray some ‘freeze spray’ but haven’t done this before and wasn’t sure which area would be best to spray.
Any advice?
A few caps were checked and were well within spec and I’d rather leave a recap for a while. Have already checked solder joins and reflowed a few suspects.
Any suggestions?
