Attention LP12 Valhalla owners
I used a strobe disk to checked for speed and it was just a little slow. I tried to adjust the new belt to a larger diameter area of the motor pulley without success. It's hard to position the belt on the pulley because of the weight of the platte... 
Attention LP12 Valhalla owners
I have LP12 Valhalla with 50Hz motor. It runs slow to me. Is there anything for me to increase the speed? Thanks 
Using the VPI SDS with non-VPI turntables
Is this means that you make the Lenco a belt drive not idler wheel drive? 
Motor and spindle bearing for DIY turntable
I used pre-owned VPI bearing and platter, Jr. or MKIII for $200 or less. Then I use the Luxman PD-121 turntable to drive the VPI platter I have to make room for 2 turntables sit side by side. I adjust the pitch on the Luxman TT to get correct spee... 
Sonic Frontiers SFP-1 Upgrades
The bigger cap in power supply provided more bass authority and the ultra fast acting diodes increased transparency and pace as I did the PSU mod myself. I preferred the stock diodes because of more natural music. 
Sonic Frontiers SFP-1 Upgrades
Letch, keep us inform about the upgrade.I tried Mullard, Bugle Boys, Amperex orange globe and A frame 6dj8. The big surprise to me was JAN Phillips NOS 6dj8 from PartExpress, these tubes were super quiet and better instrument separations. 
Sonic Frontiers SFP-1 Upgrades
If you like image and focus of the music then the SFP-1 is the one. I also like it with Denon DL-103R MC cartridge. I compared my SFP-1 with heavily moded EAR 834P, Quick Silver phono, ASL mini phono. I upgraded my with larger power supply cap. an...

Has anyone had experience with the Schroeder Arm
Mr. Schroder, Thanks for your responds and information about tonearms. I found www.diyaudio.com which more interesting to me. 
Has anyone had experience with the Schroeder Arm
Frank, Did you make tonearms with magnetic damping since 1978? If your current tonearm was in the market 20 years ago, there would not be any gimbal nor unipivot tonearm designs. I also found that the gap between the magnets can be changed to comp... 
Has anyone had experience with the Schroeder Arm
The effective mass for frictionless suspended tonearm are different than friction tonearms (unipivot or gimball tonearm). The armtube for frictionless tonearm is much heavier so it can absorb stylus energy. This energy then dissipated by the strin... 
Has anyone had experience with the Schroeder Arm
Mr. Schröder did you try to use the suspension tring from the Reference model on models 1 and 2 tonearms? And what were the results. I totally understand if you decline to response. Thanks 
Results from Beta Testers of New Formulas
I noted that with my home made and Paul’s cleaners that some surface noises still present after cleaning; but few days later when I listen the same LPs again the surface noises were significantly lesser than before. I assumed that over time the re... 
Results from Beta Testers of New Formulas
I tried the sample and it worked. It definitely removed finger prints and cleaned dirts deeply from the grooves. It even salvaged worn LPs because the wider grooves allowed the stylus digged deeper into the dirty grooves. I rinsed before vacuum th... 
Modifications to improve gain of ASL mini phono.
12 O'clock is 50% of the max. vol. with Shure V15 type 5 (3.5 mV). I think the ASL phono stage gain is about 40 dB which is about the same as my Sonic Frontiers SFP-1. Both of these phono stages are dead quite. When I place my ear about 5 in. from...
