Identify this early set please
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 |

Re: Identify this early set please
The valve sockets and coil assembly look very much like the ones in my Crosley 50 from c1924, the valve is a 01A.

Re: Identify this early set please
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 Ed |

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. John |

Re: Identify this early set please
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. Last edited by PJL; 5th Dec 2019 at 9:31 pm. |

Re: Identify this early set please
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 Ed |

Re: Identify this early set please
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. Ed |
