Fender power transformer help

layt · 11th September 2005, 07:05 AM

Ok heres my problem, the deluxe reverb Fender transformer I have is configurable for different voltages 100V,220V and 240V but im not exactly sure how to hook it up for 240V as theres no instructions. But I did find that Fender supposedly use the same wiring for all there power transformers, with the tonemaster power transformer there appears to be a usefull chart but ill see what you guys think. Ive also included links to the actual amplifier schematics. Hope someone can help, thanks guys

You will need to connect the two primary windings in SERIES..
That would be BLK/Yellow connected to BLK/GREEN ....

Then the 240V voltage is applied to BLACK and BLK/RED....

So if I join black green to black yellow that makes one side right?, then I join black red to black to use as the other? . As soon as somebody replies ill wire it up and see how I go (I wanna do it now but dont wanna destroy anything either so ill wait, thanks again)

No no no. DO NOT join black/red to black.

As cerrem said, connect black/yellow to black/ggreen. Nothing else connects to them, their only job is to connect to each other. That puts the two primary windings in series. Then connect the 240v mains to black and black/red. One side of the mains to each, NOT connecting them together first. Mains 1 to Black/red, and mains 2 to black.

Now let me throw in a little extra. See the violet wire at top? It should have about zero ohms to the black/red wire under it. That symbol between them is a circuit breaker. There is a thermal breaker inside the transformer. If you want its protection, wire the 240v mains to black and violet rather than black and black/red.

Ok ok so I went away and had a think about it and looked back at what cerrum said, then i had a look at my transformer wiring diagram and a hammond one and hey it all made sense when i used my brain!!. My power transformer works well, I measured the voltage on the secondaries and there all fairly close to what they should be. Thanks mate

I have a Fender Frontman 10G input is (120V; 60Hz; 28W). I wish to run it from 220Volts 50Hz. Does the factory transformer support 220 Volts, if not what transformer should i use to replace it.
