Realistic Lab-270 speed question

[Audio_Danger]

Hello everyone!
I have a Realistic Lab-270 turntable.
I’m setting it up in a new house and noticed the speed sounded slow.
The RPM Wow app showed the speed as 32.57.
I played my guitar along with Dokken’s “unchain the night,” and it was perfectly in key as Eb.
But the song is the key of E.

I ordered and installed a new belt.
But it still seems to need to be a tad faster.
Are there speed adjustments?
I don’t have the manual and can’t find any info online.

Any help would be appreciated!
Thanks

Yup, it appears to be hard to find a service manual but it's quite likely very similar to some other turntables. One reference says the same as a Technics SL-20 or 23. Both of those manuals are out there.

Anyway, can you take the bottom off and take pictures of any printed circuit boards and the motor? If there are variable resistors (pots) they will be visible. Cleaning those with DeOxit or similar and adjusting might solve the problem.

Thanks for your response!
I don’t feel comfortable messing with anything underneath the table.
I was hoping there were adjustments easily accessible.

but the new belt fixed most of the problem

If I recall correctly, they are -- you just need to access the trim pots from the bottom.

Little turns are all that are necessary when doing speed adjustments.
