HP 1720A SCHEMATIC 20 MISSING FROM MANUAL AND POWER ON ISSUE ADVICE

[Tacoman1234]

Good afternoon all you smart fellers, I recently got at an estate sale tons of old electronic equipment. Among the mound was a hp 1720A oscilloscope. I have narrowed down the problem to the power board. Reading the manual the +15v seems to be the reference voltage for everything in this oscilloscope. The schematic for that circuit Is number 20 and my manual is missing the page. Does anyone have a picture of that page? I have read the theory page in the owners manual and I could possible look at the board once removed and trace it out but it would be alot easier with the Schematic. Thank you for any help
