Repair of a Traynor YGL3 Mark 3 Guitar Amplifier and Accusonic Reverb Tank

This post is about a fun, relatively easy repair/restoration project on a classic piece of electric guitar/music gear: a Traynor YGL3 Mark 3 amplifier. The YGL3 is a vacuum tube -based piece of rock/music history. This project grew out of the Repair Cafe event in the Campbell River Sportsplex last month that I was a volunteer repair person for. A new friend,¬†Joedy W, had brought this amp in to the Repair Cafe, but I didn’t have the time or the parts during that busy day to do the full repair. After I got back from some travels, we were able to re-connect yesterday and I could get to work on the amp. The whole repair/restore operation had four distinct elements to it. This was a pretty interesting project for me because I had never worked on a musical instrument amp before (that I can recall), but the repairs needed were fairly easy, requiring diagnosis mainly by observation with ears and eyes and ultimately just one test instrument, an ohmmeter.
