Rays Tubes
Carpathian, it’s really not that hard to understand the differences among tubes, if you read some basic texts on the subject. Of course before substituting one type for another you need to understand how to read the data sheets.  
Rega Planar 3 upgrades
Good, easy to use protractor: Feickert. More complex to use and more expensive: Smartractor

The carpathian, yes, 12AU7 and 6 or 12v FQ7 are interchangeable, but you have to choose the version of FQ7 that matches the available filament voltage. Same specs for all other parameters, more or less.

Still wondering how west coast got hold of an SP10R platter.

How and where do you buy an SP10R platter as a separate item?   
Upgrading from. Rega Planar 6 to a Planar 8??
Mijo, since Rega design philosophy is not in keeping with your ideas on TT design, I’ve been wondering why and since when did you fall in love with the brand.

Any 6FQ7 or 12FQ7 (depending upon the available filament voltage) will out perform any 12AU7, and they’re cheap.  
Straight tonearms without offset angle
Thanks for referencing those threads, Dogberry. I read the Audiokharma thread today. Boy, some of those guys go off less than half cocked. It would be exhausting to try to correct all the misstatements.

I can’t recall who asked about the coreless motor but someone else asked what they would miss if they stuck with SL1200 vs any G series, and my response was they’d miss the coreless motor, etc. YES, the G series and now the G2 have coreless motors...

Pindac, are you saying that Stax and Micro Seiki once produced underhung tonearms with zero headshell off set? If so, that’s interesting.

There’s a thread on the Viv Float tonearm. I suggest you review it. You are neglecting to mention that such tonearms are mounted so the stylus underhangs the spindle, as is the case for all of the commercially available tonearms that have zero hea...

What you’re missing are the coreless motor, the heavier more damped plinth and platter, the upgraded motor controller (G vs original SL1200), and the improved tonearm.

Probably only an incremental improvement vs G motor controller. Possibly not audible, would be my guesses.

The G series, available since 2016 I think, is better in every way than your SL1200. Technics made a marketing choice to make the G look like the 1200, but under the skin they’re quite different, and the G series are better. Now might be a time to... 
critique my setup -- weak link? best way to improve?
Re Seeker, nearly all preamplifiers ever made operate in Class A, and many/ most modern tube Preamplifiers can drive a 10K ohm load easily (which is to say their output Z is 1K ohm or less). I agree those are parameters that need to be checked out...
