I want to buy a TAD 5F6 Tweed bassman power transformer with the folowing specs. Is 2 x 245V way to high or is even better soundwise.
Normal this should be 2X 320-330V . Wall voltage is 230V.
Primary: #72500
240V Brown
230V Black
220V Grey
0V White
Secondary:
345V@200mA Red
52V Blue
0V Green/Yellow
345V Red
3,15V@5.5A Green
0V Green/Yellow
3,15V Green
5V@6A Yellow
0V Yellow

Re: TAD 5F6 Tweed bassman transformer Voltage to High?
I think you will get a better result by keeping the voltage lower rather than higher.
You can lower it a bit (4.2%) by using the 240V primary at 230V, which will lower the secondary to 330-0-330 at 200mA.
You could also look for a Hammond 290DEX, which has 325V @230mA secondaries with a 240V primary. The 5F6A schematic shows 430V on the plates, which is at idle. A full-load voltage around 310 would be ideal, and that's about what you would get from a 290DX with a 230V input.

Thank You Martin. I go for the Hammond. Would a 310-0-310V PT bring me even closer?

If the 310V is at 200mA, and the rated primary voltage is 240 then I think that would be a bit too low.

You can check out the specifications here.
It isn't an export (240v) power transformer but you can check out the secondary voltage and current specs on the secondaries.
