Re: strange radio with no Identification
Valve lineup?
Clear pic of dial with legible station names?

Re: strange radio with no Identification
Listing the valve types might help someone identify it.
It looks a little crude in finish. Maybe some small local manufacturer just getting going? Station names can help with dating. David

Re: strange radio with no Identification
It looks interesting - 3-gang tuning capacotor and what appears to be a push-pull output stage?
Case and front panel look very amateurish though - could it have once been in a different cabinet [console? radiogram?] and someone's reboxed it as a tabletop?

Re: strange radio with no Identification
Seven valves and a 3 gang tuning cap certainly suggests an RF stage, but I can only see a solitary 6V6GT so maybe not PP, unless the other is a 6V6G.

Re: Strange radio with no identification.
Did it once have dual speakers?

Re: Strange radio with no identification.
A few odd things about this set- the speaker's very close to what I assume is a smoothing choke, the rectifier's very close to the tuning gang, surely it would be better at that empty rear RH corner? No IFT's visible (the square metal object is a screen for a signal valve), though the chassis is deep enough to accommodate them underneath! Just one signal valve by the 3-gang capacitor, maybe a band-pass input.

Re: Strange radio with no identification.
valve line up 524G, 6V6GT, 6V6G, 6F6G, 6Q7G 6K7G, one with no name on it think its a 6K7(tests ok on avo as )

Re: Strange radio with no identification.
I think Graham was referring to the speaker grille on the right hand end of the radio where there is no speaker just a flapping cloth and gaping hole.

524G likely 5Z4G. 2 6V6s make sense for P-P output but the 6F6G is an output pentode too 6Q7G and 6K7G work as det, 1st AF and IF but another 6K7 is odd, 6K8 would make more sense.

Re: Strange radio with no identification.
3 output valves, one seems to be a cuckoo?
Is 524G a typo? |

Re: Strange radio with no identification.
The dial looks vaguely like a Beethoven.

Re: Strange radio with no identification.
I agree with #4, it's probably the chassis from a console or radiogram put in a homemade cabinet. It may even have started life as a NAAFI 'morale' set. BBC Light but no BBC Third on the tuning scale indicates 1946-7. The cabinet may have been made during the home woodworking boom of the late 50s / early 60s. Several of the valves probably aren't original and may not even be correct.

Re: Strange radio with no identification.
Is the 6F6G also a typo and actually a 6F5G?

Re: Strange radio with no identification.
Barke ? Doesn't the first iteration of the 88 have a similar square screen on one of its valves?

Re: Strange radio with no identification.
I agree that the half-moon dial and the pointer boss looks a bit like a Beethoven.
The whole thing has a rather "workmanlike" air, as though it was a small scale production or a skilled one-off using whatever war surplus components were available. Maybe the 3 gang tuning cap was easier to source, and only 2 gangs were used ? The square screening cans would have been easier to fold up than round cans needing expensive presses. |

Re: Strange radio with no identification.
Judging by the station wavelengths, it’s pre-1948 Copenhagen agreement.

Re: Strange radio with no identification.
A puzzler! I think the valve line up should be: 6K7G 6K8G 6K7G 6Q7G 6V6G 6V6G and 5Z4G.
I think the rectifier should be where the infiltrator 6F6 is! There should be another top cap connection to the tuning gang and it may be tucked away. The rectifier squashed up against the tuning gang is madness. Just my guess. John. |

Re: Strange radio with no identification.
Yes I think the valves may be in the wrong places.
The rectifier next to the tuning capacitor could be in the hole where a RF amplifier - something like a 6K7 - should be.. And it would make more sense for the 2 push pull 6v6 to be side by side rather than one each side of the output transformer. Perhaps the 6v6 to the right of the output transformer is in the hole where the rectifier should live??
