Not had much mark 3 Sound city stuff come through. This has had a life, two channels are covered over, need to get the wood off see if its drilled or the pot shafts cut off.
Lots of dust inside, dry rather than greasy so should clean off fine (people are sleeping so not busting out the hoover now).
All Mullard valves so win if they mostly work. Looks like a replaced cap there.
Insides look mostly original, got that not as neat as Hiwatt, neater than Mark 4 going on. Nice resistor cluster there, guess that blew up along with the cap, think the guts of the cap were still stuck to the grill underneath, was expecting to find it exploded when I opened it.
