WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
Building, troubleshooting and testing of these amplifiers should only be
performed by someone who is thoroughly familiar with
the safety precautions around high voltages.
Hello, I am Bert and live in the Netherlands, I did ask this question at the forum in the Netherland but I didn't got the right answere. Who can tell me what amplifier this is. The transformers, choke are made bij Thordarson. Hope you can help me,
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...
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.
