Another distraction

Just acquired this bargain on eBay -

A 1940s Vortexion EG 20 electric guitar amplifier. Must be the big brother of the EG 10, as advertised in 1947.

Valves used are 4 x CL33 in parallel push-pull and 2 x EF40, no rectifier valve as metal rectifiers are used.

The amplifier is complete and very clean so my plans are to first do a minimal restoration to get it working in as close to original state as possible, then convert to safer AC use only with a modern mains transformer and 4 x EL33 to replace the CL33. Though I suppose that 2 x 6L6G would give similar performance.

I'll keep notes on the restoration here
