No sound coming from a Marshall TSL 100 head

The AC indicator glows perfectly fine, and all the tubes are lighting up fine as well. I also checked the Cab with a different head and it works perfectly fine as well. Does anyone have any idea what the problem could be?

Thanks

1. Is the output MUTE button pushed in?

2. Pull the HT fuse and see if it is blown. HT means high tension - another term for high voltage. That is a 1 amp SLOW BLOW fuse. Radio Shack has them.

3. If that fuse is blown, it MIGHT just be a fuse, but most of the time when that fuse goes, it means one of the power tubes is failing.

Beyond that, it could be many other things, like wires off, broken solder joints, open resistors, etc.

I'm also with ENZO that the HT fuse is blown. Seen it several times on these amps.
