[DOXEMF at aol.com]

Hello,
I found your info in 1959 ? TR-60 Cat.
HSM-31
MIL-TF4RX19FA
PP 6J5's 0r parallel fed 6F6 triode to AB grids
Pri-20K/5K  TRatio 1:1 or 2:1 
Sec Load Imp 20K/5K ct
 Frq 20cy-20Kc  Max Pri Volt-240v

HS(M)-29
Mil-TF1QX1OYY
Bridging line to 1 or 2 grids 20K/5K  1:2 overall
Sec 80K ct  Frq 20cy-20kc  Max Pri Volt-20

The Msuffix seems only to designate the enclosure type.
I would guess specific to Mil.

Enjoy,
Bill
