Well, it happens to all of us eventually!
Took the T-4XB off the shelf for a little dusting off and warming up,
and when I turned on, only heard a slight little 'thump' from the AC4
and then nothing.
Upon closer examination (AC4 supply had just powered one of my TR-4C's
so knew it was good) it turns out the on/off switch 'layer' of the 3
section pot has failed.
I took it apart, I see how it works - a little 'wishbone' looking copper
strap that gets shoved against 2 contacts to turn on the radio. One end
had broken off.
SO. Anybody out there successfully repaired (or rebuilt) the little
copper wishbone, or grafted a new switch to the back of the dual
potentiometer plus switch stack?
I feel like a watchmaker of late - last week was soldering the spring to
the internal movement of a Swan Mark II amplifier meter, now this?
I can put a switch in a 'SPARE' hole in the back of the transmitter for
on/off, but sure hate to lose the total ORIGINAL function of this
transmitter - other wise in really nice shape!
Any ideas boys and girls??
