I recently acquired a Watterson model 527.  It appears to be one of the last models they produced.  I believe they may have been made by the Warwick Co. and branded as Wattersons.  Either way it has a significant "motorboating" problem and I cannot seem to locate a schematic to troubleshoot with.  All the tubes (std AA5 complement) check good with my Hickok 605 and the B+ is about 120 off the electrolytics.  Any help tracking down a schematic as I do not see one under the Watterson schematic link.  Great looking radio, just want to rectify the "motorboating",  Any help would be greatly appreciated.
