I purchased the operating instructions for the Model 954 from the 'Manualman'. A copy of the units schematic was also included in the manual. The web address is "WWW.Manualman.com". I also was able to purchase Tube Test Data from A.G. Tannenbaum. Their web address is WWW.agtannenbaum.com.

Hope this helps. John
