Pioneer sx-3800 help

Sega CD · 21st January 2007, 06:32 PM

I picked on up at resale place for a great price.

It works great except it needs cleaning.

Now my question is that the quartz lock seems to drift. Is there a fix for that (like a pot)?

Thx!

maybe not a pot, but the LO coil or the PLL coil.... you might want to check the electrolytics in both the FM AFC circuit and the detector PLL loop filter.

I'm a real noob.

Can you please explain?

I looked up some more info.

I think it might be with the PLL loop thing.

Thx!

But as always more help would be welcome.
