I call this a rain drop finish using gloss black lacquer and other techniques.

Or Vampire RCAs where there is no ground tab, the ground connection is on the freaking body of the RCA, which is a 1cm^3 chunk of solid copper! How am I supposed to heat it to make a good solder connection? It's basically a heat sink. I heated one to the point that the gold plating started to flake off. Just plain stupid design.
In fairness to Vampire you can get them both with and without a ground tab, though a case could probably be made that the version without probably just shouldn't exist. Each variant has its own part and model number.

Each type has their purpose but I use wooden cabinets so I buy them with a solder lug.

I prefer these myself.

And I really like these RCA males.

Turntable is back in its home. Still a lot of work to do setup wise, but it is a functioning turntable at this point.

A wonderful turntable!

Nevertheless, I wonder if the mat, with its limited contact surfaces, might be holding it back.

Have you considered an Achromat or, perhaps, a copper mat?

Thanks, I have considered changing the mat, but not those two options specifically.
Clearly Thorens felt there was some benefit to having minimal contact with the record with this mat design, I have to wonder what they were thinking at the time.

Here are some of the exact pots for sale that I mentioned a few days ago, for this kind of money I need to put 100 or so up for sale to help pay for the audio equipment I am buying. This would be a good time not to mention what I paid for the pots. :ksc75smile: Maybe a joint listing for those and some black gate Rubycons lol. I thought there was serious money in holding onto Melz tubes but this is even better. I also have cases of other capacitors that a Russian friend talked me into buying, there is a good chance they will end up selling for premium prices soon enough.

Conducting an Auteur Classic vs. Auteur OG shootout the last few nights. My early thoughts can be found here and here.

Running the ugly Tung Sol black cans 6J5 and Bendix 6080wb in the Airmid and Tesla El51 and USAF 596 in the rectifier slot on the Lampi

I think that the consensus is that most metal 6J5 were made by RCA. This tube and the metal 6N7 are very underrated tubes.

So just how good are the RCA metal 6J5's Monster?

Theyre ok, better than average but not God tier. I'm on the lookout for some ST types but they seem scarce, so these will suffice in the interim. theyre worth having but dont expect to have your world rocked like the GEC or NU did to you.

EDIT: oh wait RCA metal? No clue, I dont have a pair. Sorry I thought you were asking about the Tung Sols.
I did just pickup a pair of GE cans on the cheap due to the + comments in the 6J5 spreadshhet, but havent tried them yet.

The Tung Sols metal 6J5 probably were made by RCA. And your description is right on.

Thats interesting. I will have to bounce the GEs off of the TSs and see if theres a difference, though my GE cans are 6C5. Did RCA make those as well?

Frankly, these “twin ring” mats were not primarily chosen for sound quality reasons, but to allow the easy removal of 7” singles and 10” LPs…
