Good scan of the original service manual. All schematics and adjustment procedures are there. It helped me to fix a long lasting problem with the tracking circuitry. The manual also includes the supplementals 1,2 and 3. Included are; electrical schematic's , pcb layout's, mechanical drawing's and exploded views, disassembly manual and maintenance procedures. 236 pages.
Excellent copies.
I will use "Owner Manual" again a second time.

Transition of the Ofs voltage during adjustment of VOL OFFSET_min
A
Example: Initial value of the set Ofs: 33 V Tentative set value of Ofs (Ofs set value for the panel inspection): 35 V VOL OFFSET_min1 (pale purpel): 19 V VOL OFFSET_min2 (light blue): 17 V VOL OFFSET_min3 (violet): 15 V
Ofs voltage (V) White A luminescent spot appears. Measure the lower limit of the Ofs voltage. 36 34 32 30 28 26 24 22 20 18 16 14 12 Ofs15V A luminescent spot appears. Measure the lower limit of the Ofs voltage. A luminescent spot does not appear. The lower limit of the Ofs voltage is 15 V.
