That's awesome Foe. I bet they look and sound sweet. Terry is the best.
I'd send the unit to him, but as you can see it is very expensive to have these beasts shipped.
I like to work on my stuff, so no biggie. I'll learn new things as well.
Mine will probably need a few zeners in the PS replaced and DC offset and center voltages adjusted.
The Quartz Locked Touch Gain control was added to later units, I believe, because of some problems in the early units. Mine works like a champ, in the "norm" position.
Best,
