There one an EL34 type explode on stage as the output had been a number of extra capacitors added to the HT before I got it presumably to reduce hum?
I used one of of these and two EL34 variants, in my youth as guitar amplifiers and PA. I had the PA cathode decoupling caps failed. Foil and electrolyte everywhere. I cleaned it up and replaced the caps, and was ready for the next gig the following week. We were very short of money in those days (mid 60s) and didn't get paid much for playing!
Incidentally I used MS Visio to do the drawing.
