Better, use some hot air and freeze mist to identify the one bad
capacitor watching out for temperature compensating capacitors that
should move. Then fix the poor solder joints. The temperature
compensating capacitors won't be in mouser's catalog, and making the
wrong choices for replacements will make it far worse. It is possible
that someone has replaced a stable ceramic capacitor with a very
temperature sensitive capacitor more readily available.
