I know it's a bit OT here, but I could have found no better place to ask my question.I have AN Conqueror, set up for 220V mains. The connections at the top of the mains transformer look like this:
/--------------\
| |
0 100 110 120 I
|
|
\--------------\
|
|
0 100 110 120The trick is that we have 230V in my country now. So should I reconnect the wires like this:
/------\
| |
0 100 110 120 I
|
|
\--------------\
|
|
0 100 110 120or maybe like this:
/--------------\
| |
0 100 110 120 I
|
|
\----------------------\
|
|
0 100 110 120??
Maybe some of you has Conqueror or similar product set up for 230V so you could check what does it look like?
Follow Ups:
My advise is to check the heater voltage for 6sn7 tube. You should have 6.3V.
The 5V 300B heater has a voltage stabilizer, so the small change in supply voltage change nothing. The same for B+.
You should adjust the power transformer primary voltage settings to get the exactly 6.3V or the closes to it value.

Sorry, the board ate the whitespaces...It is:
Lower 110 to upper 0
upper 110 to upper IShould be (I guess)
Lower 110 to upper 0
Upper 120 to upper Ior
Lower 120 to upper 0
Upper 110 to upper I
It should be:
Lower 120 to upper 0 - that connect the two winding.
Use lower 0 and upper 120 as the input of 240V.
Correction:It should be:
Upper 120 connect to lower 0.
Use upper 0 and lower 120 as the input of 240V.

Big thanks 2u all!In a meantime I asked Peter Q, he suggested lower 110 to upper 0 and upper 120 to L; I did so, at the moment everything seems to be ok :)
