The SST-30 is a 30W push-pull all tube circuit utilizing four 6V6 power tubes (matched pairs) along with tube reverb and tube tremolo with tube rectification.  Can be a beast of an amp with some serious gain.  Usually partnered with our original 2X12 cab loaded with a variety of speakers over the years from Celestion Greenbacks to Alnico Golds etc.

There is a full pdf manual linked to the right along with some quick take info below such as the tube chart and fuse location.

If you have complete loss of power to amp, likely the 3A MAINS "Slow Blow" FUSE let go which stops all power from entering amp.  First place to look when nothing lighting up.  A very small flathead can usually pry this cover open revealing this mains fuse along with a backup unless it was used previously.

The other fuse behind the traditional bayonet holder is a 500ma (.5A) HT fuse.  This is a fast blow long fuse as opposed to the SLOW BLOW short fuse in the IEC.  It deals more with power tube issue protection
