How about the old time trick of putting two low value resistors to
ground, one from each side of the
filament, used to be used for a center tap many times in days of old.
Hi Russ,
Thanks. Just to be clear, I do not require a transformer for providing filament
power: it's to fix a design flaw in the Clipperton L, which lacks a centre tap
for the filament windings and instead feeds the filaments with RF on one side
only, introducing hum.
The fix is to parallel a centre-tapped 6v transformer secondary with the
filament windings on the main transformer and move the RF input to the new
centre tap.
The Hammond 166j6 is ideal, as it can be added with no metalwork, and you
simply cut off and tape the primary windings.

Hi Kelly,
I have a Stancor P-6134 that should do for that.

Though shipping to Canada may be a dealbreaker.

Hi all,
Seeking a six-volt filament
transformer. Must be centre-tapped. To fix the AC hum
problem on my Clipperton L.
Must be about the size of a Hammond
166j6, about 3 inches wide (to fit without metalwork).
If you have something, let me know. If
I can't find what I need used, will just buy new from
Mouser.
