Trio AF-270 AM/FM Tuner
I am chasing a circuit diagram from this tuner. It is a 10 valve (tube) unit dating from approx 1959.
Mains wiring to the transformer suggests that this was constructed for the U.S. though I’m told the dual AM tuners makes this an Australian model. A previous owner has modified the wiring for 240v operation.
The unit works but output is very low, especially on AM.
I don't have a technical background and my experience is with AM sets only.
Any assistance will be gratefully received.
