Trio AF-270 AM/FM Tuner

I have a post for this under Tuners which gave some good feedback though only general in nature.
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.
Any assistance would be appreciated
