Makes even the SVT seem like a pussy cat!

Love to see underneath and a schematic. Does anyone remember the Wireless Relay Co? I used to look through the office window as a kid and remember the 18" high OP valves. LURVE one of those amps to play with but would probably need a 3P supply!

Biggest thing I handled used EL31 line OP bottles with 1200V on the TOP CAP anodes!

The guy has two more for me to look at when this is sorted, he is a DJ and specialises in retro reggae disco gigs, using vinyl. They were built in the mid '70's by a chap in Derby / Birmingham? Similar in concept to Valv-A-Tron units still made in Huddersfield, I think. (it weighs a tonne BTW :-)  )
