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.

Distinguishing method between New Tuner and Old one
If this frame is gray color (old : black), then the New Tuner (S/N:4859719730) is used.
CAUTION
2 Tuners (Old:4859717030, New:4859719730) are not interchangable. Each tuner should be replaced with the same one. But Main PCB Assy ( Old & New ) are interchangable by itself.
