Greetings,
Does anyone happen to what type microphone was with this old rig? manual calls for a T350-C mic
I am using an old D-104 and the modulation is a little low, tried another of my many D-104 and was a little better. Of course I could use a amplified D-104.
1st audio stage 6EA8 resistor was listed for 560K measured 804K replaced not much audio gain.
May be just a mic problem?
The Turner 350C is a high impedance ceramic microphone. see:
