regentone: ARG349 (ARG 349); Who has it?

I found a Regentone Radiogram in Bletchley Park. There was no type label to find.
By the tube list it can only be the ARG349 or ARG57.
Who knows the different? Are the pictures here at the correct model?

Thanks, Heribert Attachments:

Dear Heribert,

From the R&T sheets, there is little difference electrically.   I have no information on cabinets.

The ARG57 was released October 1950 some 16 months after the ARG349.

The ARG57 had the possibility of a 7B6 fitted at V3 - a 7C6 in the ARG349.

The ARG57 also had the option of a Collaro RC500 deck fitted.

The only other electrical specification difference is that the ARG57 is specified for 110-120 as against 110-130 for the ARG349 (in addition to both having a specified 200-250 capability).

Early models of the ARG349 the rectifier heater was fed from the same supply as the other tubes - later a sparate winding was added.

Regards,

Roy

Dear Heribert and Roy,

I found the following illustration in the August 1949 issue of Electrical and Radio Trading which would suggest that the set pictured at Bletchley Park is not an ARG349.

I will look through the advertisements in other issues of the magazine to try and identify the model at Bletchley Park (which incidentally is fitted with the Collaro RC500 record changer as pictured): Regentone advertised monthly in this periodical so it should not be too difficult to find (one hopes!).
