Upgrades for VPI HW -19 jr.???

Hi Dreadhead, Yes, I agree, I found out the same thing personally when surfing the MusicDirect Site, and saw no listing of the small 10-32 Audiopoints for the HW-19.

Living in Chicago basically all my life up until 3 years ago, I know Bess at MusicDirect personally, so I thought I'd give Bess a toll free call, and sure enough, they had them in stock, but be prepared for a nice sticker shock. The 4 AudioPoints came to $91.96, and the 4 brass coupling Discs another $27.96 Mark

Two comments and a question:
I don't know if they're still available, but I have my HW-19 mounted on the original "tiptoes", threaded 10/32, and much cheaper than some other cones.
Basically, I'd agree with the previous comments: I have a Jr. with RB300, Riggle VTAF, Denon 103R, and other mods to the tonearm. If your AQ tonearm can accommodate a dropped counterweight, this is a cheap and effective tweak.
My question: I have what I believe to be an older MK-4 platter, with a longer and thinner bearing spindle than the one fitted to my junior. Do any of you with experience with this table know about the earlier platters? Do you know if or how I could acquire and fit the correct bearing onto my table?

Hi Brusson, Hmm, What I personally found myself, was more, or less the exact opposite.

I believe my second hand Mk-IV upgraded Platter to be an older version as well, weighing in at axactly 18lbs.

While the Mk-IV Platter I had gotten had a much more sturdy, larger diameter Bearing, and Bearing Well, versus the original Jr Platter, I had noticed the Spindle itslef to be just a tad shorter than the Jr.
Both were 1/4"-20 threaded for Clamps. The Jr Bearing Well I had appeared to have a Brass Bushing at the top near the Bearing Well Flange, While my MK-IV Platter Bearing Well, has a Bushing made out of some sort of Black material, and I'm assuming it is Delrin, and not some type of Metal.

I'm almost positive that all Jr Platters had the bearing-spindle pressed into the Platter, while the Mk-IV Platter, such as I have, the Platter just sits on top of the Bearing-Bearing Flange, and it's massive weight keep eveything coupled up.

I notice on my MK-IV Platter itself, 3 Drilled Holes in its center, with three Metal Pins-Screws installed (The supposed 3-point support system I guess), which appear to be threaded into-through the Platter, and with Allen Head screw heads on the top-side of the Platter. Mine appear to be perfectly flush with the underside of the platter so I could not gain any spindle length by screwing in-adjusting the pins. No doubt probably not a good idea to monkey with anyway, as one would probably wind up with Platter Wobble.

I was under the premonition that later versions of the MK-IV Platters were 20lbs, and then also moved on to an Inverted Bearing? Which is yours? Mark

Hello Mark-
Well I've got a 9 pound platter, black with cork bottom, spindle press fitted, 1/4-20 threaded on top. It's 7/8" thick, the same size as my Junior's ceramic platter. Is it a Mk-3 platter? The spindle is about 2 3/4" long, less than 3/8 in diameter. If you or anyone knows where I can find (what I presume to be an older)and smaller sized bearing for it, please let me know.

Hi Brusson, My VPI MK-IV All Black Platter is not press fit to the Spindle, and yes, mine also has a cork ring on its underside, and this no doubt is to cover the Lead Ring that must be glued in to the underside of the Platter. When I say Spindle, I'm talking about what shows above the top of the Platter, and is threaded for the Clamp, and not the underside-Bearing End.

I am unsure exactly what you have there, and I'm certainly not an authority on VPI, and their history, and changes in the HW-19 product line.

I have see pics of Mk-III Platters that were a combination of Aluminum, and Black Acrylic, MK-III's that were all Black Acyrlic, and I believe all the Mk-IV Platters were all Black Acrylic, none being a combo of Aluminum/Acrylic.

This could be a very early version Mk-IV, or a Mk-III Platter you have? Only way to tell would be to give Mike a call at VPI. I'm sure he knows much more than I. Mark
