Denon DP-30L turntable problem

[FSHZ42]

I had purchased a Denon DP-30L Direct-drive turntable back in the early 80's and have kept it up nicely. The only problem that I have is that the pitch control adjustment will not stay steady! It tends to drift off tracking making the rpm increase suddenly and then slowing down past the correct rpm.

Anyone know how I could fix this problem?

Thanks,

ALMOST FORGOT!

I would like to upgrade-modify the inside if possible. I will get some pics of the inside shortly!

Thanks Again,
