High quality scan of original Service Manual. Everything´s fine!
 ;
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.
;
The Service Manual received was helpful. The electronic information is exactly what I needed.
I recomend all of my friends about this technical page.
;
