74.47.243.42
Hi folks:
I have a belt drive TT w/ a 35 inch belt. It did not come w/the original belt so I don't know how this replacement compares in terms of thickness and width. This belt rides in the center of the motor pulley so that looks good. AC synchronous motor in this unit.
The speed is only slightly fast viewing a paper strobe from VE using natural light. Perhaps just the belt. The one odd thing is you can hear an odd sound from the underside of the unit when it is plugged in but off. It goes away when you unplug the AC cord. This noise is very slight and requires very good hearing and the underside of the unit exposed to detect the noise. There is a .1 1000V cap across the AC.
Any help appreciated!

I asked them before, they are quite knowledgeable and have a very wide selection of belts to try at a reasonable cost.
Yes I ordered a .025 thick belt from them to replace the .035 thick one I have. I had ordered from them before but went for a place that was $6 cheaper not knowing there was even a thickness difference. I'll post the result.

Maybe you be lucky and someone actually has the same model...

Hi Dman,
Slightly off topic, but did you get that electronic drive TT on speed?
Phil
coffee,
I posted something last night, in response to you, but I guess that AA spaced it. Seems to be doing that a LOT lately to things I post... Weird.
Having said that; Yes! I did get the speed up to the proper range! Once I did the resistor replacement on the first R-value as you suggested, the trim-pot now can be set to around the 9 o'clock position for accurate 33.3 (see pic above to note that I have a correct 50.00hz signal now!
I also checked the mechanical accuracy by playing back the Cardas Sweep record, which has a 1kHz tone on it. The DMM reading came out at 1.001kHz, so things are much better now.
BTW, D-Wife, when she got back from her vacation, heard Madonna's Vogue and IMMEDIATELY KNEW it was at the right tempo/pitch!
Thanks again for your help (if even in making me remember how to calculate that R-value!)...
Cheers,
Dman

at first I'd preview and see the post then post and it was gone. Yesterday I posted (you can see all my edits) and it finally showed. Today gone.....I can't see your pic either..........tried mine again (pic lifted of the same TT from the net) and it seems to work for now.

Speed was my problem exactly. I used a power supply with a variable frequency output to select exactly the right frequency to lock in the 33.333 I was looking for. In my case, I was using a cheap, too-thick belt that was running the table almost 7% fast. Even with the correct belt I was 3% fast. The Eagle fixed all that and had other advantages (see my other posts on this).
If your motor is under 7Watts you can use the "Falcon" to achieve the same result. I run one of those on my VPI Scout with good results.
As far as the noise goes, does your table have a power-on light? Some of these are neon and can be noisy. I removed the light from my table and now use the Eagle to turn the table on/off.
Good luck. Hope this helps!

Yep its a .035 and I need a .025 it seems, thanks.
