Yep, check the service manual, there is a VR for tune.

After being on for over an hour (w/ power adapter, not batteries) my Poly went so far flat that I had to move the 'Tune' slider all the way to the right. Soon even that wasn't enough. Has some component failed or are there pots I can adjust to increase the range of the 'Tune' slider?
