Another DOOZY! - Mesa Boogie Tube Bass 400 Head Repair

CLICK HERE for Postmortem on this amp:    • Does Mesa Boogie Intentionally Falsif...   Well, here's another one that should have been a simple fix that ended up giving me fits and leading me on a wild goose chase instead. We'll start out with a simple recap and general clean, and end up chasing our tail in search of problems with coupling caps and the EQ board. This is the Mesa Bass 400, which puts out around 200W, not to be confused with the Bass 400+ Plus.
