Great, thanks for confirming.

@gene, I liked the video posted below. Might be the first time I saw someone measure cables at the speakers. I couldn't find a dedicated thread for this video so I'll ask my question here. I see that you addressed the issue cable believers usually have by measuring the cables directly on the...

How did you think they sounded vs. their measurements?

Have you ever actually heard them in your room or elsewhere?

You can't leave out the rest of the article linked below. What Barr says that Mueller said is quite contrary to what Mueller's 400 page Report says and what Mueller himself said in front of the cameras a few days ago...

So I guess you'd like the updated version... https://positive-feedback.com/audio-discourse/leaving-class-a-2019-redux-a-biased-opinion-from-nelson-pass/

Peter Walker used a current dumper design (some debated if it was actually feedforward) but he did NOT invent Feedforward. That distinction goes to Harold Black way back in 1928. In 1980 Sansui used a variation of Black's invention (giving him credit) and called it Super Feedforward. They...

That's a NO-NO. You need an amp switcher box.

One quality clamp is cheaper than buying several records. Some people have very large record collections so chances are that more than one or two records may have a warp. Also, some records are rare or desirable pressings and may be difficult to come by or are very expensive.

You don't have to, but many people do have some favorite records that have a slight warp. You can find tons of video proof on Youtube that show they work well (no maybe's) when used properly. I think you're confusing a clamp with a record weight.

Since you're cleaning this unit to try and get it up to snuff, I highly recommend you at least check the DC offset measurements at the speaker terminals. It is very simple to do with a multi meter. Ideally you should have 0 mV +/- 5mV on each channel. If you are +/- 15 mV you are still fine...

Don't get carried away with the cynicism. Clamps do work for records that need it. You can actually see a warped record flatten down to the platter when a clamp is used properly (sometimes with spacers) ...That is a good thing and will have audible and visible (speaker cone) results.

You don't have to turn them that many times. Use your judgement based on the results you get. I only suggested that many turns (gently) because it seems the pots are either really dirty or the previous tech has not been doing a thorough job cleaning them. You really just want the fluid to get...

Is that a knife edge? BTW, you're painting with a mighty broad brush when you disparage "far eastern" turntables. There are several "far eastern" turntables with "stock" arms that would give what you have there a walloping.

Yes, it is possible. With a turntable, every small adjustment matters (as does equipment, phonostages, etc.) Remember, there is a rock being dragged through the grooves of another material. Any resistance that is not optimal may come through as you describe. Not to mention the TT itself, wiring...

Which cartridge alignment method did you use?

That's right, don't open the pots. Especially if they are the type I suspect are in there. It's probably a small sealed circular can with a few tiny holes. Spray into the tiny holes. If there is no metal enclosure (an even more basic pot) it's even easier just spray it directly onto the wipers.
