1967 Supro Trojan tube combo amp,  10" speaker,  several months back amp had been gone through and serviced by amp tech used by a music store,    works and sounds great,  looks like the Ruby and RCA tubes are new,   the tremolo was serviced and works great,  don't know what else was done.   When plugging into a 3-hole outlet or power strip face the G on the plug end toward the ground hole in the outlet.     These are hard to find and should be a good investment whether Jimmy recorded with this model or not.
