Hey all,

I have searched quite a bit and just can't seem to find what I need, but then again I'm not familiar with working on these devices so that may not be saying much.

Could anyone show me where on the board of otherwise the speed controls are for 33 and 45 records?
I have the unit fairly disassembled but still upright at the moment.

My unit typically works well otherwise, although occasionally the stylus arms don't want to move all the way in and make contact with the record when you press play.

Thanks in advance for the help!

Check out page 26 of the manual, down and right of the main chip on the microcomputer PCB. That's the vague location, how it's all connected is shown earlier in the service manual. If you're lucky something is apparent on visual inspection. It's for the 3000 but I'd have to imagine it would have a similar configuration in the 3500.

I've got a 3500 with the same issue, just have yet to have the time to get around to fixing it. That or my 2000 with a cracked record PCB.

If its anything like the vz 2000 , there are 2 vr pots on the PCB located on the back of the turntable.

Thanks for the replies! I'll try to post a picture or to for posterity here tonight if I can.

hifiengine.com has a lot of free service manuals, this one included.

Here's what it had to say
