FYI: VPI HW-19 motors

Bob...yes, sorry the SIMS Navcom Silencers are long gone, but they do show up on here every so often. Keep an eye out.

You could also do a "wanted" ad for them. I'm sure there are some people who have them and haven't used them in years and probably have forgotten about them

They really weren't designed for the VPI HW-19 tables in mind as suspension pucks but work wonders.

Mofi--John from Audiogon--not sure of his username--has pointed me to an ad for a VPI TNT Mk5 Platter and Mk5 Stainless Steel bearing/spindle. I believe it will fit my HW19 II and he suggests it as a major upgrade. I'd be interested in your opinion. I've emailed VPI and asked them:

1) Will it fit?
2) Will it be a worthwhile upgrade?
3) Will it require a new or different belt?
4) Will the increased platter height be an issue with my SME IV arm?
5) Will I need to do anything with the suspension (I have original springs)
6) Can they suggest a worthwhile suspension upgrade?

You've suggested the Navcom silencers and I'll looking for those. Do you have any comment about Herbie's products?

Thanks in advance for your opinions. I can also be emailed at bwhitlock56@gmail.com.

Bob...here are my answers:

1. I'm pretty sure the TNT MKV bearing well is the standard
1" diameter. The TNT MKIV bearing well is 1 1/4"
and the hole needs to be enlarged, but really isn't that
hard to do unless you have the MKIII stainless steel plinth.
It can be done, (I've do it several times), but requires a
lot of patience and a pretty sharp enlarging bit and a
variable speed drill. You need to go slow when drilling
stainless steel. I burned up 3 drills the first time I
tried this before I figured it out.

2. It will be a MAJOR upgrade.

3. Same belt

4. Most tonearms require the "Super Armboard",
but the SME IV already is a pretty tall arm and should have
plenty of travel up and down. The regular armboard is
1/2" thick the Super Armboard is 1" thick.

5. You will probably need to change out the springs to
compensate for the extra weight of the platter. If you
could find the SIMS, that would take care of that.
Hopefully VPI still has the needed springs?

The difference between the TNT MKIV and MKV platters is the
MKIV is 1/3 delrin and 2/3 stainless steel. The MKV is half
and half. I have both and think the MKIV to be better
sounding, but the MKV is very good and will be a great
upgrade to your MKII platter.

Thanks for your response!

If you don't already use them; the SAMA and SDS also make major contributions to the performance of the HW-19.
