Both sets work surprisingly good, espcially the sound quality of the tube set is impressive, even though the output tube is not really strong to save battery capacity. To the restoration: Both sets usually have massive problems with a built in rechargable battery which leaks out it's acid that causes a lot of corrosion usually. Also the handle is usually broken as well as the antenna. Finding a good example can be time consuming and expensive too also these radios are quite wanted and sell fast usually.

@Sandy: No probelm, here we go:
The aluminium box in the lower right of the first picture is the shielded DC/DC converter. The circuit on the Pertinax board are the insides. As you can see this radio is hand wired and quite well made. The cabinet is made of wood covered with a colored plastic foil. Not to mention that you could buy 3 small FM only mains powered tube radios for the same price back when this set was new  The leaky waxies are already replaced with axial styroflex and mustard caps in these pictures. I bought this radio from the widow of a well known radio collector who passed away some time ago. So there also is some sentimetal value in this set. Last edited by Josef; 07-01-2019 at 02:43 PM.

Danke, Josef ! I have a few German AM/FM/SW sets, & marvel at how mainly, they did everything w/just 5 tubes, too. American sets, to the best of my experience, pretty much always used at least 6 or more often 7.

But if the bateries leaked (sheesh, I can't imagine how is to have leaks from an anodic battery) the electrolite impregnated into the wood of the case it can be a problem or it dosen't smell bad?
Did you ever seen and Austrian tube portable radio that had F.M. (U.K.W.) 88-108?

The leaked out acid causes excessive corrosion on the aluminium chassis and discolors the wood. The problem is that there is a built in NC battery which leaks terrible. So event though if you remove all batteries you can't avoid the built in battery.
At least there is no smell left over because everything is dried out since ages. To be honest I don't know an Austrian tube portable radio up to 108 MHz. Even though early transistor radios went up only to 100MHz. Mains powered tube radios which went up to 104 MHz were available in the early 1960.

I just bought a Grundig Transworld on Halloween while buying a couple of Philco TVs.
It was for sale, the first tube FM portable I've seen in person, and the price on the lot of items was right. I brought it up on the variac and got hum and tubes lighting but no reception. I need to find a schematic and dig into it.
