Hello again,
I'm wiring up the OPTs for the SSE, and my chosen transformers' wire colors don't correspond with those on George's wiring diagrams. I have the Toroidy TTG-EL34SE
The output side is clearly labeled, so that's no question.
But the input side is a source of confusion. The UL tap is clearly labeled, and then there's two wires labeled A and +U. Is "A" the anode? And +U is...?
Each OPT connector on the board has three contacts. I can see that UL goes to contact 2 if connected, but I'm not sure which wires should connect to contacts 1 and 3. Which goes to contact 1? A or +U?

Hi,
I looked up the details on your output transformer and can confirm you are on the right track. “A” connects to the Anode of the output tube, and “U+” to the (B+ in American nomenclature) high voltages supply. I tried to find a clear picture of the SSE PCB to try to distinguish between connectors 1 and 3 on the PCB, but was unable to do so. However, hou should have no trouble determining which of the two has continuity with the HV supply. Perhaps George’s wiring diagrams will help too:

Look at my 3rd pic here.

This is a bottom view of the board. Outputs at the bottom of the picture.
The blue wires are the anode. The red wires are B+
