Got to play with some nice tables today.

A batch of nice turntables by Buhduh, on Flickr

plus this one, a Kenwood KP-990. I installed and aligned a cartridge and cleaned it a bit. Works great :

This Denon DP50 (also in the first pic) seems to have a bit of speed fluctuation and cleaning the pots has not quite nailed it? Capacitors maybe? It also will need some lid polishing.

The Victor (JVC) JL-B44 had a bent tonearm tube which I've straightened and aligned well enough. The plastic on the rest was also broken, but that glued up nicely. Buttons were sticky but they have responded well to some lube and persuasion. Speed pots cleaned and adjusted.

This was after straightening the arm somewhat but I made it even better. Ideas as to the model?

And now I'm having a listen to this Sansui SR-929. It's just going to get a bit of cleaning and polishing as it works well. After I'm done with the this the owner is going to bring me his 828.

Nice decks Monty!
Try cleaning (DeOxit) the trimmers inside, not just the pots. Measure them. If they have dead spots, replace them. Doesn't hurt to replace EC's.
 
Those are definitely some pretty tables, all of them. I have to say I rather like the look of the JVC with the simplicity and the separate drive.
 
Thanks guys.

I am going to check that Denon over more before shotgunning the caps. I'm also going to look at the power supply requirements. It wouldn't surprise me if they all (except the Sansui) say 100v.

Not the Kenwood too! :(

I have seen North American 120 volt versions, though not lately.

Well the 100v thing doesn't scare me. The Kenny, Denon and the Victor with the Grace headshell all run at 120v but the new owners should use transformers if the design calls for it. I have one and a variac too so am good here. Main Electronics or Lee have stepdowns for around $30.

I have not had the 838 in my hands yet, but will probably see it in a week or so.

And I did confirm that everyone of these (except the Sansui) are all 100v models. It makes sense knowing the source, but I will will have to talk to the new owner recommending the transformer(s). I test the Denon briefly today with an autotransformer set at 100 and it didn't show any speed anomalies. The test wasn't long enough to be conclusive though.
 
One of the Victor motor units definitely needs work. While one worked fine on the 100volt transformer, the other started very slowly at the 44 setting and only slightly faster at 45, essentially with very low torque. On both settings it would get up to speed eventually but it took a few seconds rather than the nearly instant acceleration you expect of a good direct drive. I switched it on and off a few times to see what might happen and it died completely. That might just be a fuse, but based on the symptom just prior I doubt it.

An a better note the Denon cleaned up nicely and held stable speed after a few hiccups at the beginnng. Both of the Victors also suffered from sticky buttons but some lighter fluid and well placed oil helped.
