Found a BUSH EBS24 radio (24" wide tabletop model, gold metal dual grilles) Are these rare? International version has multi-tap tranny for all world voltages (as originally required 240v for transformerless series-string filaments?)

Bush valve radio

British transformerless set, wooden case.

Valves: UF41, UCH42, UF41, UBC41, UL41, UY41, UM4 or UM34.

Coverage 524kHz to 30MHz (no gaps) in 6 bands.

These valves are 8-pin miniature with a lump on the side near the bottom. This lump matches a cutout in a small metal shield which is part of the valve socket.

Doesn't seem to be particularly rare (in Europe) from what I can see.

I don't know anything about an international version with a transformer. If that's what you have, then it could be rare.

The valves might be ordinary 6 volt ones instead.

Has original series-string with 45v filamants, thus for Orient/Americas must step-up mains to 240v. Has really nice collectable 8" Celestion spkr!

A valve a day keeps the transistor away...

The valves are clearly the 8-pin type, while the tuning indicator looks like it might be the UM34. The transformer is obvious too.

If it was made in Europe or Russia I'd say there might be a chance of it working as is, but my experience of English sets is they use wax caps that leak, and filter electros that short out. No photo of underneath, so no idea if that applies here.

Brought up to 100v on a Variac, runs good with just a Croc-clip jumper for aerial!
Sound incredible with its big Celestion speaker!
Very bright German Magic-Eye tuning indicator!

Its Magic Eye is maybe an EM48? And has low hours. Will have to investigate further.

One must be cautious with European radios. There are Philips ones where the printed circuit board is hot as well has the tubes and Europeans' often used what looked all the world like a transformer and it was in fact "Hot Chassis", or close to. as that was not a transformer: It was in fact a tapped ballast.

Aside from that, the top of it looks downright dangerous.
