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

I found my measurements of the Victor concealed brass piece and measurements of the gasket I found at home depot

I will take the 7082 I just bought apart when I receive it, go again to Home Depot, find the part number, take pics, measure the inside diameter this time.

I'm looking for the part number of the washer in your diagram.  I don't see it.  Do you have the number?  If so, and if you would share the info, that would be great.

Lew; It’s apparently a back burner project for Thom but involves a new machined stub… My enthusiasm for it…whatever it is..has waned over time as my arm went back to Tri last winter for the CF , wire and other upgrades… a hyper clear sonic change for my system anyway…

Re on the fly… and “ grub screw “…. generally i agree…but my 505… the Dynavector is a glorified grub screw….

lewm,

you are the reason I will take it apart and go find a washer that works and make a note of the part number when I do. Arm is about to ship from Japan.

I'm hoping everything is good inside, won't know till I take it apart. If not I have 60 days to return it.

Elliot, That is a very kind offer, but please don't go to the trouble. I have a big bag of faucet washers, many of which have a promising profile, and I can find one that works by trial and error and thanks to the dimensions that you posted. I've got an excellent metric caliper that will help too.  Keeps my mind off you know who(m).

The DV505 VTA adjuster is not so great compared to that offered by many modern tonearms, but it is light years ahead of the family of tonearms that place an actual grub screw at the base of the pillar with no gearing to keep the arm stable while you move it (by hand) up and down.  The DV505 at least has a gear built in to move the pivot up and down in small increments, and it's relatively easy to secure the adjustment once you are satisfied.
