Ok I plugged some effects unit into the effects loop of my jcm 2000 head and after about 30 seconds of playing the amp went silent.

I found that the ht fuse had been blown so I replaced it. Now there is sound but it's very quiet. As far as I can tell all the tubes are lit up and considering I replaced them in January I can't imagine they'd be out again but this is my first tube amp and I know nothing about how they should work.

What is wrong wit the amp and what should I do???
