In the process of troubleshooting a faulty Drake TR-4C, years ago, the root cause was traced to a non-working PTO.
A visual examination of the mint-condition PCB revealed nothing. Component checks with a multimeter also showed nothing amiss.
Then 'Eureka'! A continuity test showed that the PTO coil was isolated from ground.
A closer examination of the PCB, with a magnifying glass, revealed a dry-solder connection at the ground end of the PTO coil.
Just one solder touch-up and the old workhorse was back in business!

I can’t believe that my good friend, OM Guru – VU2GUR, is no
more.
He passed away on Saturday, 8th December 2018, after a brief illness. He was 78 years old.

| OM Guru - VU2GUR |
It’s been over 30 years since OM Guru and I first met. We
found we had a lot in common and hit it off right away.
That led to daily HF / VHF QSOs and visits to the
local Sunday flea market, which he often referred to as ‘J-land’. We also exchanged that occasional shack visit to work on a homebrew project or troubleshoot a boat
anchor or whatnot.
We teamed up for a few foxhunts and won a couple of them too.
OM Guru was always enthusiastic about anything related to amateur radio. He
spared no efforts to help newbies come on the air. A high point for him was his
gaining proficiency in satellite operation. He shared his experience with
others and helped them work the satellites too.
I can never forget the good human being that OM Guru was.
May his soul rest in peace.
