Identify this early set please - UK Vintage Radio Repair and Restoration Discussion Forum

Hi Folks, just starting on an early set from the collection of unknown origin, but believed US, any thoughts gratefully received.
This is a 3 valve set, 2 tuned circuits and appears to have a loading coil for the RF stage.Valves are WECO types I think and look to have a single side pin bayonet fixing, holder diameter is 1 3/8". It looks like RF, Det, LF with provision for phones or LS.
It appears that 2, Crossley transformers were originally fitted, one is now missing. From the position of the transformers it may even have been a reflexed set.
I doubt I can find valves for it now, but an easily reversible mode would allow PM types to be fitted
Any thoughts on the valve types that would have been used?

Many thanks, Ed

The valve sockets and coil assembly look very much like the ones in my Crosley 50 from c1924, the valve is a 01A.

Hi John, many thanks for that. The reaction assemblies look very similar.
Mine has the number 89397 stamped on the back of the panel.
I forgot to say that the fil rheostats are also Crosley parts

Hi Ed,
Mine has a filament rheostat as well but yours has more modern? tuning caps', mine has the book type which I'd never seen before.

I was going to say American but I am beaten to it.

This looks like the one https://www.radiomuseum.org/r/crosle...n_regular.html

The bad news is a complete with case and valves one sold for $32 on ebay USA. I really must get my brother to ship one of these US 20's sets over.

Thanks PJL, that looks like my set.
In addition mine has the switched loading coil shown on the circuit but not apparently present in the Radiomuseum picture, screwed to the LH vertical inside the cabinet.

Now I need to sort some valves or adapters

Many thanks, Ed

This page from the web may be of interest as your missing valves are probably of the 01A type of which there seems to be quite a few equivalents,

Hi John, thanks for that but unfortunately my set has the bayonet type of base.
I think I may be able to modify a triode like the HL2, if it is a short bottle, by fitting a pin to the side, so it will go into the base and I can still close the lid.
