Anyone have a single 12AX7 mic preamp schematic?
I could roll my own for a change...

I can't tell you how many hams had nothing other than a crystal element
D-104 microphone being run straight into a single 12AX7 as their first
speech stage. And 99% of 'em sound good enough to hear on the air.
You certainly don't need -all- that, to be heard...
but I -would- like to hear you on the air on 75m, sometime.
