Default Gainclone is on 120 volts will it be fine at 220 volts?

Hi,

I have a gainclone it runs it has 18 VDC secondaries at 120 VAC. So at 220 VAC it will run at 33 VDC, no? If this is correct, is it okay or should I look into a different transformer?

Is the primary rated for 240VAC?

I got it out of a 120 VAC ampliphier. Does that mean it's rated for 120 VAC probably? What might happen at 240 VAC? Good things or bad things

Speaking for myself, if it was a single primary and not dual, and if there was nothing on it saying it was rated for 240VAC, I wouldn't try it. Plus, surplus transformers at cheap $$$ abound.

I beleave it is dual. It has two pairs of 18 VDC and some other pair that's some other voltage that is a lot higher I beleave?

I have two other transformers, but I don't know if they are rated for 240 VAC. I do know they came out of 120 VAC amps.

"Dual" as in dual primaries. If you have 2 primaries, and they were wired up to the mains in parallel in that amp you took it from, you can wire the primaries in series for 240VAC service.

I beleave it has dual primaries. Two other wires I have taped measure 120 VAC and a third one. Also taped off crossed with one of the other two gives 240 I beleave.

How would I wire them in series?
