Thank you Mike.
It all looks original, the pot is the same as yours in the picture, the wiring is the same, colours and layout.There is a single bare wire off the tag with the braid down to the side of the put can, again it looks like original as the wire is through the hole in the tag and the braid soldered on top.
Its very strange. I have another DAC10 somewhere. If I can find it I will have a look at that one.
The trader sheet doesn't show the screened lead but the maker's sheet details it exactly including the braid connected to the cathodes and not the chassis which again is unusual and I can see no reason for this rather than conventionally grounding the braid to the chassis.
Its working now with a low distorted output. The HT is low, only 146v with 50v on the anode of the UBF41 triode but there will be several caps leaking. I have changed the cathode cap ,it was toast, and the grid cap on the UL41 had a good leak, further I have yet to explore.
Thanks for the help.
