Hello- Have two identical transformer sets out of FAA AM transmitters.These
units were set up as follows : pair of 6C4 mic. amps driving pair of 6146
modulators modulating a single 4CX150A.
Here are the corresponding transformers : { input}dual 150 ohm windings to
40K ohm @ 25 mA.
{interstage} 10K to dual 75K
windings
{ Modulation }1,2,3 = 7500 ohms CT
2,4 = 3500 ohms @ 200
mA. rated 80 watts
All transformers are 300-4000 CPS, sealed types in nice shape.Fairly
compact and lightweight units for their
