the S-3000 manual and schematic is here if you need ithttp://www.one-electron.com/doc_archives/Sherwood3000.pdf
Why did the detector tuning change? Here are some possibilities - The power supply voltage changed (PS caps going bad), or the tubes on either side of the detector (6BN8 and 6AU6) changed (are wearing out), or the tube pins are dirty.
