Before you start any refurbishment I recommend to download user, service manual and schematics for your equipment. It’s much easier when you know what to do and how to adjust it properly.
In part 1 I’ve bought TT, brought it home and done thorough research; purchased all needed parts.
in part 2 I’ve rewired tonearm, upgrade it and clean turntable
- cartridge upgrade
- tonearm rewire
- reservoir refurbishment
- exchange record clamp
I was quite happy with results of previous refurbishment, but I still didn’t reach as good sound as my MSB Platinum DAC III. Something was wrong…
So I have decided to replace phono stage Aqvox Phono for brand new Whest Audio PS30R. I’ve had quite serious problem with hum and Whest Audio absolutely solved my problem – it is dead quite. Also I have get the rid of Denon cartridge and purchased Benz Micro ACE SH.
As I find later, those el-cheapo silver wires were coursing a lot of trouble, they’ve been springing, therefore proper setup of tonearm was absolutely impossible. Therefore I rewired tonearm with silver litz cables Van den Hul MCS 150M Internal Rewire Cable.
Van den Hul MCS 150M is available to purchase in metre lengths from Analogue Seduction
Silver plated cartridge pins from eBay are used again. Soldering of VDH is very easy and isolation also works as flux (still I alway add some extra)
Van den Hul MCS 150M is the finest tonearm cable. Great performance without bullshit (Not like overpriced Audio Note tonearm wire). It’s not cheap, but certainly worth every penny. For those who want cheaper solution I suggest Pro-Ject copper tonearm wire.
The MCS – 150 M consists of 7 individually insulated very pure Matched Crystal Silver strands each 80 micron in diameter incl. insulation. It’s so fine, that it doesn’t influence tonearm performance in any way. VDH suggest it as the best possible interconnect if braided from 4 lengths litz wires together. It believe it must be good, but bloody hell – sooo expensive to be made!
One day I was playing record it the sound was somehow weird and unsettled. After quick look It was noticed, that platter is rotating too fast, speed cound’t be adjusted. I took a platter off and find out, that hydraulic oil reservoir which adjusting speed come off – it was glued by double sided tape and after all those four decades full of abusement and grease environment basically come off.
I scraped tape off, sand it and degrease it with lighter fluid. Surface was ready for cheap eBay epoxy glue 🙂
Epoxy glue gotta be hardening for at least few hour. What is better ballast weight than Reel to reels and bunch of CD’s? If you do it, do it in Audiophile way!!!
It was cleaned, brushed and re-attached with epoxy glue. Hopefully forever now. Looks neat and will work than before.
Another upgrade was new MC cartridge Benz Micro ACE SH, SME doesn’t really need Stevenson’s protractor, but it could still move a bit.
Trackability is very fine now and downforce was set to 1.9g. Just about on usable edge of 3009S2.
Detail of MC cartridge Benz Micro ACE SH with 3009 S2 fixed headshell. It’s pretty pain in the ass to mount it with screws because of absence of stylus protector (cover). You wouldn’t believe how much I was sweating 🙂
Front view – blue acrylic looks great.
Boronium cantilever is very fine and groove noise is very low thanks to fine stylus shape. It somehow doesn’t click and pop as for example my Ortofon 2M black. Stylus holds at the very bottom of the groove and doesn’t plowing dust and mess.
Jelco stabilizer – record clamp / weight from Jelco company is truly a beautiful piece of engineering. Machined solid brass, gold plated. Fine felt at the bottom side
Weight: 328 g, Diameter: 80 mm, Height: 30 mm
Transcriptors Hydraulic ball bearing dimension is 1/4″ / 3.5mm in diameter.
After about hand an hour of fiddle adjustment the TT sounds amazing. Again, I had to adjust overhang, VTA, downforce and antiskate, but it was well worth it. I have past all test but two for the fist try with Hi-fi news test record. I forgot to mention, that this is amazing record and anyone who mean it seriously with vinyls should have on. It’s not cheap, but last forever. You can purchase it from Analogue Seduction.
And how new upgrades improve sound quality? I have to say, that I haven’t even expect so good sound. I’m not chasing shadows and I don’t believe in superiority of vinyl sound over CD. I would say, that some CD’s sound better, but also many LP’s sound better than digital. It’s pretty good result for 40 years old TT don’t you think? A bit of rumble in background, but nothing I wouldn’t be to live with. On the other side Hi-res tracks are different league. I suspecting that they sound so good, because they’ve been remastered that way.
