Got it, thanks @Dr_DX.

Anytone 6666
How did you determine this? Are you saying it 1kc off what the display says? my 8 digit frequency counter and i also own 11 other radios and another 6666 this 6666 is low on lsb and i can not find a service manual for it my other 6666 is dead on as are my other radios

Thank you very much! Geez, finding any tech info on these rigs is harder to find than hen's teeth !
Thank you @Dr_DX.
I have e mailed Quixiang asking about a service manual with alignment info and no reply.
I also e mailed CRT France about a manual for the SS9900 with no reply.

That's top secret stuff during the times we're in. Maybe in 20 years it'll be declassified.

The document from Dr_DX is titled "HAM MobileCom 1011". Might be more clues in that direction. I found a modification for SSB something?

So went through it all, that mod pix, was inserted in a discussion in those few posts in the thread about modulation. I haven't tried to translate the text notes on the pix. Just the post text. Went through the translation (Thanks google) on all the other pages. Nothing about alignment or documents. Near the end someone had the same question about the service menu and the defual settings , as the post someone linked to in an earlier post here just recently.
I should have learned some technical German instead of just the street slang for drinking and... ummm... other fun things.
Looks like it's a modification for SSB tuning (Umstimmung) that doesn't affect AM or FM. Which sounds like an "unlocked clarifier", but only on SSB. Could be for tuning the IF, though, to change the center of the SSB signal. I think it also kills auto squelch (ASQ) in SSB modes.
They do tell you to glue the wire down so vibration doesn't make it break at the solder joints, which was nice of them to do.
They add one transistor based on the part number given and the author says (I think) it's what he had on hand, so the it sounds like any transistor that's close in spec should do. The added transistor has it's collector connected to the component with the red dot, the emitter to the zero ohm resistor, and the wire connects the base to the collector of another transistor, shown in the picture. I can't tell if you're supposed to isolate any component leads before adding the transistor.

D'OH!
After a little more reading (slowly), this mod just turns off the auto squelch in SSB. That's it, that's all it does.

That's exactly what I got out of that one mod.. yes... There were earlier posts w/ complaints about the squelch performance. I thought there was another set of posts complaining about modulation. I might have confused that pix with a fix for that.
Well reporting back on the about 4 year old quad 6666 that is the primary go to.
This is the first of two quad 6 that I own and it's been the best ssb performer I've ever owned.
Now, the follow-up is
channel encoder is damn near becoming unusable. It's been finicky from day one and was for certain that it would be the weak point in this radio and it shows to be true. I've noticed that in the recent months it has started to get worse and after heavy use last night I think it's had it.
As common as these are nowadays, there has got to be someone out there with an encoder to replace these.
I'll continue to use it and changing channels via the mic but sure would like to repair it.
Anyone here know of a possible parts source?

Replying to myself here and hoping this could turn into a solution because the channel encoder can drive a guy nuts.
I'm thinking this might possibly be a compatible replacement for the quad 6. Am taking the jump and will report back.

Encoder (CH Selector Switch) SR-655HPC & SR-955HPC 10 Meter Radios
If your channel selector switch on your SR-655HPC or SR-955HPC is giving you problems, here is the solution. These are high quality with a slightly firmer positive "click" when switching channels.
