As you may well know , there are no more AM stations in Germany and there has been a flood of German sets on the market , well I bought this beautiful pre war and no piano keys in sight RADIO. Its a Eumig 329W. I am sending photos.

Photos uploaded.

German thoroughness at its best.

Two remarkable items jump out at me;

a) Shielding to the RF valves TC's are what I would term "armoured" screened cable. I've seen such work in old aircraft ignition cables.

b) Dust coat around the speaker. Marvellous---simple but effective protection.

Great find TC.

Pleading now------any chance of taking a peek underneath??

Be careful with it until you work out what you have. The Europeans are as bad as the US when it comes to "Hot Chassis sets" only they can be a lot more sneaky. Sometimes, that which looks like a transformer, is not. Sometimes its a tapped ballast coil.

Check the Chinese Hat, style caps on the RF tubes. I often find the insulation snapped & have to fix them. Also beware of the red Philips valves, if you dare pull them out by the envelope & its loose, you can break the bond between that Metalisation & its earthing pin. That metalisation is the valves shield. One looks like its been repaired already?

Pin 1 is the predominant earthing pin, but not always.

I am afraid it will be a little while untill I dismantle it lol. What looks like a transformer is separate from the main Chassis, Why would this be?
If any of you want any of these sets please let me know as I have contact details from the supplier.

What looks like a transformer is separate from the main Chassis, Why would this be?

Could be an AC/DC set in which case it may have a hot chassis. Be careful as you go with that.

What likely needs to happen in the ideal world is get a data sheet. Radio Museum has it listed & its exactly what I thought it may be.

It has a balast & that's a hot chassis. One preferably works on one of those with an Isolation transformer and you cannot earth it nor use mains powered equipment the leads of which are grounded. No metal workbench, or the kitchen sink.

These are intrinsically unsafe and that uncovered tapping is a death trap in itself. What can happen with many American ones & probably these, is that the active can end up on the chassis. Often their antenna is meant to ground via a line cap to neutral: which as pointed out can end up on active. All caps that are exposed to mains voltage should be replaced with mains approved line caps. Often that extends to any external antenna connection where a line cap (0.01mfd?) should be in series with it.

If there is no back make one so that no metal part can be touched. I have a valve tester like it & that I have a note on to run from the isolation transformer. A visitor that should have known better, failed to do that & the circuit RCD soon sorted that out.
The question is of course how did it and a couple of bits of test equipment with two wire cables & a cap to the metal body to the mains cable, get into the country? If the cap fails the whole thing could be alive?

I always use a isolation transformer in every test I do. And it does have a Back.

All good even a knob coming off one of those presents a risk. I will not always use the isolation transformer, it rather depends on what's being powered. One must remember that the cable has to be compliant, & I always insulation test the primary side of a transformer set minimum.

Because of the RF & Lightning here, the isolation transformer has Filter caps & MOV's. The other Mod (It's a lighting one, continuous rated) was to add a kill switch. So you can literally have "your finger on the button". If it is going awry, you can kill the power swiftly.

We need to point out to those who read things on the forum, they are made aware of "risk" and when it comes to fiddling with mains radio's etc. Its on your head: "Caveat Actor" applies.

The (US) NEMA two pin plug can be reversed, hence the comment of Active being able to end up on the chassis: Ours can't do that and we enforce wiring codes. So its mainly a case of ensuring yours has its chassis wired to neutral.

Do note that the isolation transformer will have a Neutral & Active on the OP. If you want to make sure all is dead, use double pole switch's. Several here are.

Ah, beautiful radio.

Could you get a list of valves? There appears to be a sticker inside which may contain the information.

The valve line up is EK2, EF1, EBL1 and AZ1, and I will send a copy of the schematic. Its AC only.

Looking that up on Radiomuseum, it seems they sold both an AC and a DC model of that set. I guess they used the same chassis for both models, but added the transformer for those who wanted the AC model.

The voltage tap selector switch appears to be live, too. Dangerous.

Thanks for that Brad. It looks pretty straight forward.

In Germany, radios used to be taxed by the number of valves they had. This led to interesting designs and multi-function valves.
The triode-pentode output valve with the top cap (EBL1?) in your radio is such an example.
