Peter Traynor built these things to stand up to road abuse, unlike a lot of vintage stuff.
Clean out the broken tubes, re-tube it and play on. De Roche Sound sound is solid and clean; if you need distortion you'll have to add it with a pedal; I play hard rock; The sound is loud clean and fat, and can compete easily with any today bass amp reference especialy plugged into SVT cab. It's more power than any right thinking guitarist would ever want. Don't expect to be getting power tube distortion out of it - it's made to be a bass amp.
Most of the plastic logo's broke off of these amps and cabs so it wasn't unusual to see "raynor's", "Trayno" or "rayno" logos swinging when you moved them. I never modded it because it was perfect for my needs as is.
Can be converted from to EL34, I think a pin jumper is needed.
The schematic for my '69 Custom Special says to use an 8 ohm load.
