Can any Oracle experts help me?

Hey there,

I picked up a used Delphi Mark V a few weeks ago and man is the set-up getting to me! I finally managed to properly calibrate the suspension as per instructions and everything seems level and balanced - but I can't seem to get the belt to rest in the middle of the motor pulley. No matter what I do it seems to "want" to move to the bottom of the pulley. I hear some pitch instability - most obvious on piano recordings of course. The manual lists "belt not riding in center of pulley" as a potential reason for pitch instability but does NOT explain what to do about this or how to fix it!

Any insights out there?

Thanks for your help!

You got a lot of guts buying a tt like that without knowing a good set-up person. Best of luck.

If I were in your shoes, I'd call Oracle. I'm sure they've seen this before and can offer some advice.

Where are you located? I can recommend someone in Southern California.

I'm located in Toronto.

I'll probably just call Riendeau at Oracle - send an email but haven't heard back - have read that they can be slow responding to emails but can be very helpful over the phone...

It can be tricky to get the belt to sit right.
I place the belt around the platter then use a finger to put the belt on the pulley, always keeping tension on the belt so it stays put on the platter. Spin the platter by hand a few times to see if it is seated right.
Seems like you need three hands, but with practice it becomes easy.
If the belt slips to the bottom of the pulley, I remove the platter and try again
Do you have an instruction book?
