But I am having difficulty in understanding the power supply arrangements.
There are 2 bridge rectifiers but only the output of one seems to be smoothed. The other has nothing at all to smooth the DC.
Hi Sam,
I had a quick look at the circuit diagram and it's certainly a bit hard to follow....
The output of the second bridge-rectifier, eventually reaches C67 (1000uF), so it is smoothed, it's just been drawn in the vicinity of the output stage instead of near the bridge....
Good luck in getting it going.

Thanks Andy,
I see that now. Not the usual way to draw a circuit.
Considering the pi network to smooth the other bridge rectifier, that seems most odd to me.
I will attempt to get the cord drive restrung today, after I have glued the floating tag strip back onto the speaker basket.
Grundig quality certainly seems to have taken a dive in the '60s.
Boater Sam.
