Help with Rotel voltage reconfiguration

....turned out that the 2-pin plug of the charger autonomously decided to crawl out of the socket, vertically. :clown:
Ohh...maybe that's why nobody answers my calls 😀

Actually, I just replugged the monitor PSU and the phone charger myself so it is some consolation to know that
even with different mains plug/socket designs, globalisation leads to very consistent global product failures too.

Skippy? A bit too "gamey" for me but bon apetit - plenty of seconds where she came from. :yummy:
 
Hello i buy an amp in the usa with a voltage of 120 volts and I would like to reconfigure the 240 volts, can be changed or not ?
thanks for answering me

"TP" probably reads TF = thermal fuse. I am guessing right now it's going mains --> TF --> 0 V -(primary)-> 115 V --> mains or something like that, right? (The second 115V winding should be either unused or wired up in parallel to the first.)

You will have to wire up both 115 V primaries in series with correct phase. So you should disconnect the wire from the 115 V that's in use now and rewire things accordingly. There is no standard for this, so the first 115 V will have to be connected to either the second's 0 V or 115 V with an extra wire (I'd try what's right next to it first).
Nothing bad should happen if you get phase wrong, you just won't have much output voltage to speak of (because you just wired up the transformer as a big common-mode choke and the magnetic fields of the two windings cancel out) and things obviously won't work.

Make sure you put in an appropriate mains fuse. Take out the existing part and read out its value, maybe with a loupe. You'll need one with half the amperage and twice the voltage rating, same kind of acting characteristic. You might find something like a T 4 A 125 V, which you'd replace with a T 2 A 250 V.
 
There is 2 wire of 115 volts orange and brown where can i connect it ? i send you a picture on it.
