Update on this issue, I bought a new L41, D2 and a dual gate FET from KD7DNY
and the rx is greatly improved. Likely an alignment will put the final 
touches on it.

I also bought the new Elcon VFO stabilizer and finished installing it just 
now. After 45 mins,
NO VFO drift indicated on the display. Much better than the K4DPK I was 
trying in there
so will stick with the Elcon.

https://shop.elcon.ch/yaesu/universal-fll-vfo-stabilizer-el-34-2.htm

Also treated her to a full bandswitch cleaning, new Sylvania 6146B tubes and 
a neutralization,
as well as an IF board mod to improve the audio and a better cooling fan for 
the finals.

After many long transmissions, the cover for the final cage barely is warm 
and I have good audio reports.

Very happy with the results reviving these Hybrids back to life. One day I 
may advertise a repair service for them.

Message-ID: <04D54577A6544C6F8CE060CE4F2A35FE@HAL2000>

After asking a Kenwood expert he said Inrad (International radio) makes good
filters for lots of radios.

"For a TS-830S, a pair of their 400Hz (1st-2nd IF) filters will put the
stockers so far to shame it's not funny."

I am guessing he means these:

Has anyone ever used their stuff before? Kind of expensive.

Fox-Tango originally made many of the "higher class" filters for many of
the 70's/80's Kenwood, Yaesu, and Icom rigs. I believe Inrad became the
new owners in the 90's (or maybe late 80's). They have always been
expensive but they are great quality and work extremely well. I have a
#94 and a #96 filter in one of my TS-830's for super great contest
operating and DX chasing especially in crowded band conditions. 
I think I have another identical filter set still sitting in a box on the
shelf that's never been used.

Pete,?Yes, the original "Fox Tango" filters was a company started my Milt Lowens, N4ML (SK) back in the 70's and focused on the original Yaesu FT-101 series hybrid radios, and successors. He was located in the South Florida area and? ran the "Fox Tango" club. Milt published a monthly newsletter which had interesting stories about the Yaesu hybrid radios of the day (101E, 101ZD, 102, etc). The original Fox Tango filters were only designed for use in the Yaesu hybrid rigs, but later expanded to the other brands (Kenwood, etc). Milt eventually sold the company to International Radio (INRAD), which I think went through some ownership changes and is now owned by Vibroplex/INRAD.?Bob K3AC?In a message dated 9/16/2020 10:45:42 AM Eastern Standard Time, manualman at juno.com writes:?

INRAD filters are known for having sharper skirts and better shape factors than the manufacturer's xtal filters. Some are designed for simple 'drop in' replacement; others must be wired in using mini-coax cables to the IF board.??Bob K3AC?In a message dated 9/16/2020 11:54:45 AM Eastern Standard Time, k5xu at comcast.net writes:?

I have both the stock Kenwood 500 cycle filter and the Inrad 250 cycle
filters in my TS-450's.  The Kenwood 500 cycle seems much wider than 500
cycles.  The Inrad 250 is like a brick wall.  No comparison between them.

I would spend the extra bucks and go with Inrad.  73

Seems healthy, just starts at 2500. 40 and above are fine.

I have a TS-570SG with no transmit audio via the mic jack. Digital
transmission via the ACC jack is fine. Receive is fine. Swapped mics with
same results. It has been sitting steady on my operating desk for years. I
use it at least one a week and lately everyday on digital. I have not even
opened it up yet. There has been a problem from time to time with transmit
audio drop out, but if I wiggled the mic cord near the connector it would be
fine for a month or so. Using the original handheld mic with coiled cord. I
am the original owner for 10-20 years.

Any ideas where to start?
If I don't fine a mechanical connection problem, I will have to send it in.

Where is the best place to send it from Georgia?

Problem solved. Somehow the mic gain got set to zero. It may be a weak
battery since I have never changed it. I could have hit the mic button and
then later turned the multi control to do something else.
Thanks to all who helped.
