Have a large radio-phono combination. It appears to be TRF with an AC power supply. Looks like 5 stages of TRF. Chassis is gold in color with a small blue Zenith tag stating Model 40A and s/n 212333. The mechanical push-button assembly states Automatic Radio # A-18900. I am seeking schematics and any other info.

Originally purchased the unit at an ETV auction in Pgh (WQED) about 1970 and was told it was CA 1928.

Hi Curm

There is a Zenith Model 40A built in 1928. Information can be found here:

Thank you Norm.

Have downloaded and printed the schematics and they appear to be correct for the radio chassis. Any ideas on the record player?
