Re: [TenTec] 9420 manual

[Perry Ballinger <w8au@sssnet.com>]

To Gary and group:
My TT 9420 developed a problem of not energizing when the xcvr (Paragon) 
was turned on.
Problem was the 15 Volt "keep alive" circuit had failed.  The small 
transformer feeding this
circuit went open and the current TT folks have no replacements. There 
is no such xfmr
in anyone's catalog.
Had to configure a small multi-tap xfmr I had in my stash and hardwire 
it in for 240 VAC
input.   Result is that my 9420 is permanently wired for 240 V.

Wonder if anyone else had this xfmr failure?
