Jack,
That's why I hesitate every time I open up the Cambridge 220. What's even
more scary is when you're working on a 50,000 watt FM transmitter and you
get something in the wrong place and draw a 3 inch arc that sounds like a
shotgun! I guess that's why I quit that business, not wanting to die of
heart failure.
Could you determine exactly the spot that arced when your wings were put
back? Do you have a manual to trace out the Sfzd circuit? I love the
Sfz...although that alone is not "wife friendly" when she is present. I
wanted to see just what those two 100 watt amps and speaker cabinets would
do, so when she was gone, I ear-plugged up...and "opened it up".
Unfortunately, one of the speakers was up against the stairway wall, and I
developed a fairly large plaster crack right behind the speaker, on the
other side of the wall. Sure blows your hair back a lot better than the
Moller Artiste Pipe Oprgan I had!
Good luck in tracking down the problem...
