Hi George,

The Zenith 8G005 also has a push-pull output but uses 1LB4 tubes. You may be able to convert to 1LB4s (Same electronically as 1Q5s but will have to modify the circuit for cathode resistance to maintain correct grid bias.

I am not a fan of junking a historical radio but someone may have already done so and the transformer and speaker may be available. Specs for both tubes can be found on the internet. Check Ryders, nostalgia Air, etc. for the schematics for both radios.

Best Regards,
