Title: HELP!! My Mod transformer blew!
Post by: WB6VHE on August 27, 2005, 02:50:09 AM
Hello fellow a.m.'ers!

Anyone out there have a UTC S-22 mod xfrmr or something with a similar footprint?
Mine blew this evening during a QSO :'( :'(, and the layout is cramped for space.  I have
a bigger piece of iron, but it won't fit on the chassis.  Hope someone can help!

73,

What do you have for space?
How many watts of Iron?
We will look around with the tape measure.

Thanks, Keith.  I found one that I think will fit.
Just in case you have something suitable as well,
the dimensions are: Height = 6.5"; width = 5 3/8";
length = 6.5".  250 watts.

Now I'm looking for a 50 kHz I.F. transformer, ala Hallicrafters SX-100.

73,

If it's still in the radio, why not repair it?  Unless it's physically smashed, I've had almost 100% success in repairing IF xformers.

Hi John:

The IF xfrmr is for a project, not to replace a bad one.  I have a bunch of 14.5 Mhz IF cans
(don't know what they were for, but are brand new, made by National)....it appears
my junk "box" has come up empty on this one.
Thanks for your support!
