I realized some 50 years ago that all connectors are not created equal.
There are good connectors and "good looking" connectors. Since we
primarily intend to use the connectors and not "look" at them, then one
should be aware of differences. If the connector does not have the
company name or MIL number on it, then it is most likely only a "good
looking" connector or counterfeit knock-off. In fact, regarding some
of the ham fest connectors, I'd be ashamed to put a company name on
them too. Be aware of no name connectors.
Amphenol has been a leader in quality connectors for RF. Cannon and
Neutric are good for audio brands. There's others but be aware there
are many counterfeit connectors in the market place. Bargain connectors
generally turn out to be NO BARGAIN because they cause issues, now or
later. You've spent several thousand dollars on your station and you
are going to trust its operation to a $1 connector? That is false economy.
Also, when soldering the center pin on a PL-259, do NOT let solder build
up on the outside of the male pin. It will expand the center contact
when inserted into the SO-239 and problems will abound.

And discard those "Amazon Special" PL-259s. Use only quality connectors. It is
not worth it to use off-spec connectors - you are witness to the pain and heartache they
can cause.

If it were me, I'd replace the SO-239 on the tuner... That way, you
know the issue won't come back to haunt you later.
