Hello dear friends,

I have quite unusual problem with this apparatus.

Just to mention, I have quite experience with old radio restoration and reparation.

Problem with this radio at start was completely destroyed power supply section, do to previously reparation atempts.

It was all misconnected, but with diagram I downloaded from our Radiomusem site, it was quite easy to correct all misconnections, but!!! after I resoldered and checked all connections, after switching on, on referent point where it should be -9.1V, I measured -20V, and output tube anode start to glow, all other voltages were too low, and minus g1 was -3.6V (see picture). So I started to check again resistors and capacitors arrangement, replaced UL41, tried another output transformer etc..., but nothing happened, too much current flows, and quite simple problem is now headache....

Does anybody have an idea?

Thanks in advance, Peter.

Replace 10nF capacitor between UAF42 anode and UL41 grid. It has too big leakage current
