Does anybody have information about this model?

After resurecting an American version of this radio, I am amazed to find that it came with a partial circuit board (just the amp section with tube sockets in it), bipolar electrolytic capactors on the speakers, use of of an EF86 in the amp section, to just name a few things.

It does lack the build quality like its competitors, SABA, Telefunken, and Grundig, but the big speaker and the push pull amp, makes this radio a "screamer"!

Since there is no schematic on RMorg. , I had to sort of figure out what's going on, by using the listed schematics for the 408/3D and 410/3D models.

The only major flaw is, that they placed the self biasing resistor directly on the circuit board(rated at 1 watt). Of coarse, the resistor was open, and needed to be replaced. When I recapped the board, I placed a 5 watt sandstone resistor seperated from the board for heat disipation.

Is there any advice someone can give regarding the tuner/clutch mechanism?

Thank you

Omer
