Hi guys,
I've just bought a broken Denon PMA250 II Audio Amplifier off eBay, and I've tested it and found that the transformer is kaputzed. It's only putting out 1.5 V AC so I'm guessing there's something a bit wrong there. I'd like to get a new transformer for it, but I don't know what the output is. The amplifier says 130W power consumption on the back, and I've heard somebody with a Denon PMA 250SE say that it's transformer is 2 X 30 VA output, but that was for a different model so I don't want to rely on that.
Also, I've tried taking the transformer into Maplin, but the thick students in there (IMO not qualified to be working in an electronics hobbyist shop) "didn't know what the output was", "didn't stock big transformers", and "didn't know where else I could get one..." derrrr..... helpful!
I wondered if you guys could offer any help here? Even if somebody could point me towards some schematics, or where I could get hold of them. Thanks, Mike
