Hi Bill,

No personal experience here in the construction of IF transformers, per se,
but here's the website address of that fellow who does make his own:

http://web.telia.com/~u85920178/blocks/if-txfmr_tube_00.htm

I always figured that if you can make a coupling coil for HF (as in the RF
transformer coupling an antenna to the grid of an RF amplifier tube), then
building an IF transformer wouldn't be all that difficult: the frequency
would be a LOT lower, for one thing, and that's always a "good" thing!

Anyway, FWIW...

Hello Fellow HBR'ers,

Must confess right here: Several years ago I purchased several parts from
one of the HBR gurus.  It would be for the HBR 16.  In the meantime have
decided I should probably build the 13C.  Sooo, I finally took out all the
parts I have and placed them on a basement table as a sort of impetus to
begin the job in earnest.

The recent traffic on the reflector, (re: IF transformers) has set my head
to thinking.  I don't have the 1600 IF's, so will have to scrounge or build.

MY QUESTION: Has anyone recently and successfully built these?  (I might
have to tune them to 1610, based on what I already have on the table.)
There is a British fellow in Sweden who has a website up about building the
IF transformers.  Does anyone have experience in this area?

My chassis is rather large (from Hammond, I think: ca. 17 x 9 x 4), so I can
pack in the goodies.

ciao
