I have bought a radio, which I think is pretty nice. It will go nicely in my office for fm listening, as we cannot get am in the daytime. I love the magic eye, also. This might be worth having French polished.

As a general caution about vintage electronics, it's not a good idea to leave such radios operating when you're not close by. They have been known to self immolate.

Yes thanks GTC. When I say office- I mean a room with a laptop.. just me. And I only run my present radio- tecnico fortress- when I’m there. I’m rather nervous about fire, having read Brads comment about a radio nearly killing him. I unplug it from the wall when I’m not there. But very good advice.

Yes, a Kriesler plum pudding with a power transformer, most likely overloaded by an electrolytic condenser. I never bothered doing a post-mortem - everything was covered in soot and transformer varnish.

I admire the Mr Bean painting job some electrolytic caps achieve, when the set is powered when it should not be and they explode & powder coat the insides: Seen a few of those.

Marcc,
Thats quite funny!
I have had a quick look through the schematics, and I've sent them to the local newsagency to get printed as large as I can. I saw a 100 μF electrolytic in there I think- this is quite large, not available through the usual channels of supply.

100μF is unusually large and is probably not present in any Australian radio. The Germans do like to complicate things with their circuits.
