[GreenKeys] 5763 one-tube TU

[hwhall at compuserve.com]

It's in the 1969 ARRL Handbook for sure.  12AX7s, 12AU7, 6Y6G tube lineup.  I still have the coils & current meter I used in one I built about 1972.

Reminds me of my first TU using the W2PAT design.. about 1969-70 era  which used TV width coils padded down to audio
frequencies for the input filters.   Can't find the circuit diagram and not sure what tubes I used,  maybe 12AT7
and 6V6.
