The 4-pin rectifer says "pre-war" to me, as Thordarson used octal rectifiers in the amps I've seen made from 1946 on. Though it's probably home built - the control marking doesn't look like a commercial product. They DID make a 1950 amp with two 6V6s, a 6SL7, and a rectifier, but it wouldn't have had two extra socket holes... List the transformer part numbers and I'll see what they fit...

Hello Tom, the numbers on the transformers are 6754, 49C21, T40096 end T14C70. The former owners told me, that in the missing holes two tubes 2A3 were.
Hope you can help me,

Greetings, Bert

T14C70 is 22 Henry, 5 mA, "tone control" choke. The others may not be catalog parts - Thordarson started with "T", used "C" in the middle for choke, "S" for output, "R" for power, "F" for filament, "D" for driver.
