Hi there,I could be wrong but it looks like the 2 - 100 ohm resistors on the hum balance control are burned up,usually means a heater shorted to ground,or to the plate,(sometimes).Also the AC cable is missing,along with an output tube,it's probably blowing fuses if you power it up.Somebody's been in there changing caps and messing around.Good restorable project,but I wouldn't pay a whole lot for it,just my 2 cents,Mel.
