Victor UA-7082 Arm OR Micro Seiki MA505L ...? (both fit my existing alternate 270mm hole)

Disappointedly, my early model Blackbird Arm post is not as tight a fit in it’s arm base tube as Thorens or SME precision. I had NewArtVinyl add a 2nd allen head set screw (current production change along with the 5 pin din connector so you don’t need to terminate the silk covered Litz wires yourself like I did),

I need to loosen two set screws, adjust the height up/dn, tighten two set screws; definitely not ’on the fly’. but their micrometer method provides for ’precise’ up/dn

you put something between the plinth and the micrometer’s tip so the arm stays where it is when it’s set screws are loose, then turn the micrometer for up or dn: not easier, but more precise than any arm I have adjusted. You can record the micrometer’s settings if you want to recover prior determined positioning.

Look what I just found, I forgot this discussion I had started in 2019 when the 1st 7082 was on it’s way (it arrived damaged, I returned it for a full refund).

What am I looking for?  I see the entirety of the old thread.

I find it humorous when a google search finds something I created that I had completely forgotten about, a chuckle, then I forget again. I didn't read it yet, just wondered if you remembered it, maybe something useful there.
