Working on a SX 43 and am wondering if others have run into this issue. I have reception on all bands but only when I connect my long wire antenna directly to the RF adjustment pot for the corresponding band. I have not tried to connect my signal generator yet as it’s a little intimidating compared to other simpler radios I’ve aligned.?
Any suggestions would be appreciated. ?
I have replaced the all the caps including the filers.?

Re: HA-1 T.O. Keyer socket gnds
Had a strong 60hz hum in my R-388 after removing and replacing the front panel. Couldn't figure out where it was coming from. Turned out to be a heater string returning to ground through the frame of the headphone jack. Poor contact due to paint.? Scraped off paint and p ut a star washer on the jack ?No more hum Key was the frequency.

We
sometimes forget that a chassis is often a high-current AC
conductor, sometimes carrying several amps of tube heater
current.? To Don’s comment, bonding to a single common
chassis point often reduces or eliminates induced hum and
buzz.?
?
Someone
mentioned using balanced heaters and a hum control balancing
pot.? That’s excellent advice, but during production,
manufacturers would typically wire the heater bus first,
then overlay additional wiring like laced cable harnesses.?
In many transceivers with dense wiring practices, it’s a
real challenge to replace heater wiring with a twisted pair
without disrupting components and existing wire runs, even
if attempting an overlay.? I once tried to balance a Collins
KWM-2A’s heather string but gave up: a point was reached
where collateral damage started to occur owing to
under-chassis packaging density.?
?
On a
positive note, I replaced the AF amps in my Drake R-4B and
R-4C receivers.? The goal was to get hum/buzz down to zero
with the AF control wide open.? With a screwdriver connected
to the AF amp’s ground lead, I wiped across the chassis in
search of the lowest hum/buzz level.? I found several points
that met this criteria.? Once found, a hole was drilled in
the chassis and a solder lug added for the ground
connection. ?At these points, AC heater ground current is
minimal, sometimes cancelling altogether.?
?

Hey John,? That's a very common practice in audio gear,
naturally, to avoid ground loops.

Steve, had the same problem with a 32S-1.? I used a pair of needle nosed pliers and squeezed the center contact connector fingers closer together. Worked fine.? k6lr?

I replaced the RCA jack with a BNC jack in My Heathkit rigs.? My
Henry 1KD-5 amp also came with a BNC jack on the input side.

Hi, I have a SR-150 which I
am refurbishing.? The phono (RCA style) RF output jack is
somewhat unreliable, even though it looks to be in good
condition.? Is there an upgrade suggested to replace the jack
with another connector?
Thanks for any comments or
suggestions.

Bob,

There was a fella on here that had several made and was selling them. I think I have an old back cover. If you don't get any responses let me know. You can have my old one.

Probably a long shot but I was wondering if anybody here might have a back panel for a P-2000 power supply that they would be willing to part with??
