I use a (self discharging) Peak Atlas ESR meter for quick in-circuit testing - looking for out-of-wack capacitance, and secondly sketchy/ESR If it were mine - I would begin by quickly determining the (%) health of all the Electrolytics. There appears to be a whole bunch of Electrolytic capacitors in your late 80s - early 90s set. It could be anything from a - dry-joint - to a failed/sketchy component. Well, this is what trimmer capacitors are supposed to do !īe-aware - anecdotal evidence found on the internet can often be nothing more than ONE man's word. When I turn it, sometimes the station it's tuned to comes in strong, so I assume it is the problem component. In regards to the trimmer capacitor: You said that you. You said that you reseated connectors - are these Molex or ribbon connectors - did you clean/apply some IPA or other "magic-juice" to the connectors.Īs I'm sure that you already know, many ribbon connectors are fragile and easily broken.īatteries, their connectors and the aforementioned board connectors can oxidize with the passage of time.Ī pencil eraser will often remove this from large connection points.
