Hot Rod Deluxe Problem

[Ronsonic]

Is it just me, or does it seem that most repairs come down to dirty pots and jacks and bad solder joints? I seem to have about 75% or higher incidence where the entire repair consists of cleaning pots and jacks and finding bad solder joints/traces. I've gotten to the point where I automatically clean stuff and then re-flow all jack and pot connections and then test before I even start to get to the "down-and-dirty" troubleshooting. Most of the time, the troubleshooting isn't necessary after that. Has anybody had this experience, especially on newer (<10 years) amps?

This is a major portion of my life as a working bench tech. Most faults, especially intermittent ones are mechanical.

Solder problems are found with single sided boards that are wave soldered. Current Fender and recent SLM products are pretty notorious for these issues.

Dirt sounds like dirt. Clean is good.
