[AMRadio] Requium for Tranny?

[Gary Blau]

Dave:

Ouch.  Sorry to hear that.
Sounds like WZ1M's offer to rewind might be attractive, unless you can
find another 500 xfmr somewhere (good luck!).  That's a great rig so
it's worth the investment.  

Now, to find out why it went bad in the first place...
Best of luck.
