Mike,
Hey! It's good to run into you over here. (I'm Jim the S-10EV
owner.)
Glad to see your TT experience worked out. It really does seem to
depend on a number of variables (board preparation, paper, toner,
time and temperature.) It looks like you nailed them all. Good for
you.
BTW, I'll have to order one of those fuse boards from you, too.
Jim
