I just sold an on the air ART-13 and
ARR-15 receivers for $1k. The ART-13 was complete and
virtually new condition. The ATC (Navy designation)
and the ART-13, both T-47s, are virtually the same. I
would shoot for the easiest one to get on the air. I
might also recommend an a.c. power supply, to begin
with. That will allow sequential application of
voltages; filaments first, the 400v, then the 1100v
HV.
Things to sequentially check:
All tubes light up.
Autotune works and properly "homes". (
no home, no TX key).
Apply 400v and check grid drive.
Finally, apply HV and check for power
out.
If you need initial dial settings for
test on 75 meters (can provide).
You will need between 700 and 1100pf of
loading to tune 75 meters at 50 ohms.
Been there, done that, at least 8
times.... It can be done.
