I’m not on the Audiogon Forum much. I get a weekly email titled Weekly Recap which has some of the top discussions of the past week, I guess.There are many belt-drive tables out there with adjustable speed that will stay locked at the set RPM. A few that come immediately to mind: Rega P8, Acoustic Signature Wow XL (and every model above), and the Gem Dandy Polytable Super12. These are just a few of the more affordable ones. Once you get into Palmer/SME/AMG territory, nearly all have adjustable pitch with some type of speed lock. You invest in a KAB SpeedStrobe and you’re good to go. My table has adjuatable pitch in 0.1% increments and according to the SpeedStrobe, it holds speed within 0.03% of perfect. The controller keeps it stored in the memory so it need not be adjusted again unless I adjust cartridge setup.
I was very intrigued by this thread because I’ve had a Bluenote Bellavista Signature turntable for about ten years now.
I’ve replaced the U3 tonearm with a suped-up Rega RB300. Incognito wiring, Pete Riggle VTA on-the-fly adjustment and Michell counter weight.
Don’t think I can live without the on-the-fly Vta anymore. I found the unipivot a little to squirrely for me.
I recently had to replace the motor because the original crapped out. Luckily Goldnote (which Bluenote is now) had one left in their old inventory. I also got an original belt which is essentially a giant O-ring.
Anyhow, I noticed that it runs pretty much right on at 331/3 rpm but when I go to 45 rpm it runs fast. I’ve tried everything to get it to run correct at both speeds. The Bluenote uses a hollow belt spindle with a threaded insert that can be screwed in or out for minor adjustments of speed (it makes the belt spindle bigger or smaller). My thought was that if it’s right on at 331/3 rpm then when I move the belt to the 45 rpm spindle groove it should be right on or close without having to make a speed adjustment to the spindle insert. It doesn’t and won’t, even if I try to adjust the speed using the spindle insert.
I hope I explained that well enough to understand because a lot of folks are not familiar with this turntable.
Because of this problem and not being able to rectify it I’ve been thinking about a new turntable and I’ve been a little drawn to the Technics because at this point I just want something that RUNS AT THE CORRECT SPEED.
It bothers me to no end that I know the speed is off. Even at 33 1/3 sustained piano notes sound like they’re slightly out of tune (maybe that’s just my imagination?). 45 rpm just doesn’t sound right at all (definitely not my imagination).
I’ve been wavering back and forth on which way to go.
A belt drive with speed controller or just an all-in-one DD such as the Technics.
Remember, it has to have on-the-fly/easy VTA adjustment.
Thanks in advance, Nick.
P.s. I won’t jump on anyone for their suggestions even if they’re a so-called "fan-boy". Not that there’s anything wrong with that. :-)
Now keep in mind that speed accuracy is a moving target, because not all laquers are cut at a perfect 33.3 or 45. From what I’ve researched, few are cut at a speed any more accurate than that of a budget turntable.
