Default Re: Regarding home made TRF

The signal level required by the 6V6: 12 volts p-p, or dc measurement with a AVO?
I would like to boost the audio somewhat if I can.
Have any of those members who've built TRF radios been able to follow the signal through the set with a 'scope?
I need to know what sort of signal level a EF39/6K7 or a EF91 would give used as a detector. Then I know what sort of additional boost I need to arrange with the extra triode of a 6SN7GT.
