This may be a long shot but nothing ventured,
nothing gained.

I would like to build a simple CW/AM rig.  I am
looking at a project to build a four band
miniature phone-cw rig in an August 1953 issue of
QST.

The modulator uses a driver transformer.  Single
plate to p.p. grids, ratio 2.66:1.  Suggests a
Triad A81-X.  This is not critical.  I can always
add another tube to get the p.p. grid drive, but I
would rather use a transformer if I can find one.

The other item is a 5-watt modulation
transformer.  Calls for a 50ma. secondary. 
Suggests using a Triad M-1X.
