Looks like the 28 volt supply is gone, nothing out of the
transformer, so guess the winding went open. This belongs
to a fellow ham and know he wont want to go the cost of
another trans, so will just sneak in a little trans to
make up the need for control voltage. It'll work fine.

Thanks for the interest

OK. Remember that this winding grounds the center tap (white wire).
I assume you checked for corrosion, etc. on Molex pins/plugs (and ruled
this out).

If this is a three- tube .. a Hypersil would be a nice changeout (Peter
Dahl).
I have talked to Alpha from time to time --
I think Alpha also uses a similar size one in the current amplifiers.

When sizing the add-on - remember that the 28 volt line:
Supplies the 8874 control grids and is used as a "bucked" winding for the
blower.
