Hi Walter, accuphase service manuals are really hard to find because service centers, still providing service for very dated products like yours, have no interest in disclosing such documents. I gave up on looking for DP-70V service manual and just relied on the inscriptions on the PCB.
DP-90 runs over KSS-272A pickup and the servo board, as far as I recall, has no trimmers for tune/adjustment. What's the problem you're having with this device?

I know that it is hard to service
Tell alter
I had a similar problem with a few recently purchased CDs and an Accuphase DP-70V (see this thread). Despite I completely recapped the servo board this has no major effect. The things improved a lot by slightly adjusting the focus bias trimmer on the laser head but was not funny and not easy given how weighty these devices are and how discomfort is to adjust a tiny trimmer on a pickup on magnetic rails.
