Diagnosing a bad power transformer

Hey guys,

I've been having some issues with my 100w plexi kit. I'm wondering if anyone can tell me how to figure if my PT is no good.

Symptoms are:

- The amp is about 1/4 as loud as my JCM 800 100w head at full volume
- I have a very audible hum coming through the speakers that sounds exactly like the PT hum when turned on
- The first few months I had the kit together the Mains fuse blew almost anytime I tried a new power source.
- The amp sounds pretty great though other than the really high noise ratio. Lots of hiss.

I'd be grateful for any input.

Thanks,

J-C
