# What's wrong with my1943/5200 Mosfet Amplifier? Blown on first run

I have just brought an 1943/5200 mosfet based amplifier board. Shopkeeper said it's rated for 24-0-24 AC.

So I connected it with 24-0-24 transformer like this in image below.

As soon as I turned the power supply, I heard a loud hum from transformer, Like it was on full load. and few seconds later cap. on left side blown. (I have also got a loud noise from my speakers also like I have passed 24VAC through em.)

I have no Idea why this happened. Did I made some mistake? Is circuit is actuality meant for 24-0-24 DC? What now? can I still revive my circuit? What are the components which might have died in the process? are my mosfet's are still okay?

That the amplifier needs a DC supply, not AC. The + G - is a strong give away. An AC power input would likely have a pair of ~ symbols.
