Hello Friends,
I have a mantel model AWA Radiola in a wooden case that I have had since 1933 or 1934. I believe it is described as the 'Empire State' style. It worked until recently and it would be easier to repair if I had a circuit diagram and any other documentation regarding operating voltages etc. Its serial number is A7251. I have a circuit for the Model 37, which used a 6D6 for the RF amplifier whereas mine uses a 78 (and always did). Superficially, the circuit of my set seems to match that of the Model 37, apart from the RF valve. I replaced the wet electrolytics years ago, otherwise it is in original condition, although the speaker cone has seen better days.

I would appreciate any information you can give me.
Regards,
Peter James

G'day Peter,

Your radio sounds like an R27 of 1934. I have such a beast here that I am halfway through restoring. I trust that yours has a round dial glass which shows the AWA logo when the dial lamp is on. If so this will confirm it is an R27 and like any Empire State, it is definitely worth hanging on to.

The only thing I don't have for it is a circuit diagram which may help you though another member may be able to assist in that regard.

That description & number sound familiar. Definatelely had one of them acros the bench. I believe I know who has it & there was a circuit.

They are not that radical. The Variant of an R301A that I have passing through at the moment, is radical. Never had anything that performs like it, or a bigger swine to fix... had to draw it's circuit.

I will follow up R27.... may be able to get / have circuit

78 is 6K7 spec.

Here's a picture. Unfortunately it is the only one I have of my set. Despite the name of the photo it is a complete receiver now, including the long lost escutcheon and knobs.

It will be a while before I can produce a new photo though, I am still waiting my turn at work on using a laser cutter so I can make a new speaker grille - the original is beyond repair unfortunately.
