Yes OK Jim, thanks for your input. In addition to the VFO problem,
I see now that there is no grid drive on 160 or 80. So maybe a good
idea to fix that first. The VFO seems to be a weak point in the DX-100,
but other areas are easy to fix- audio etc. This DX-100 was a parts rig,
and I found all the parts to put it back together. Working on 40 meters
just fine- except for the reverse tracking on the VFO. Should have tested
it before remounting it in the rig. Trying to get around removing it
again. The potted iron in a DX-100 make it a great project- well worth
the effort.

Russ:
Your story sounds like the problems I had with my DX 100. Low to no
grid drive I traced to the socket for the 12BY7 and after replacing
it the thing took off like nobody's business (there were some other
minor components weak as well).
I changed the coupling caps in the audio circuit, increased the
decoupling caps and put in a little negative feedback. I get better
reports than before the mods. Don't know why I have a soft spot for
the DX 100 but it is really a good radio. Have fun with yours.
