Thanks, I may take my chances with simplified ground wires in place of those $#@$! braids.
Today's puzzler: What the Heck?!
Here's my cleaned up tuner assembly. Two gangs have leads to the caps of the 78 and 6A7 tubes.
But then there's that little tan (was white?) wire between the mid and front gangs. Hmmm...
And at the front gang- the wire is merely looped through the lug- no solder, and that lug has NEVER had solder. It's clean.
Those two gangs are not supposed to be connected at all. The first gang should be connected to Grid 0 (pin 5) on the 6A7, and to some lug on the band switch that I haven't traced yet.
Any ideas?
