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.
I came across a power transformer that was in a Dynaco st 70 that does not have any familiar numbers on it to me. Was wondering if anyone has a clue as to who made this? The numbers stamped on it are; 464006
