Everything in the manual was excellent except for a couple of pictures of specific areas in the unit that were a little dark. Owners Manuals re-sent the pdf file & the problem was corrected. Excellent product! George

Thanks for offering this item at such a good price. Proved handy in identifying the part I was looking for my set.
Thanks again.

This is the original manufacturers service manual, with detailed info on the circit boards, explosion drawings of all parts in assembly order, and tuning instructions. The only thing missing is the information on the dimensions of the various drive belts. mail me if you need them. gcrossman_at_aol.com

This is a high quality manual with clear schematic and components layout diagrams ; with service procedure included.
[PWD signal] After plug the AC cord into outlet, VP voltage appears on the base terminal of transistor Q3. When the VP exceeds 16 volts, Q3 is turned on by the differential voltage between base and emitter terminal of transistor Q3. Then the PWD signal goes to GND level and informes � Power ON � to the CPU. When the VP drops less than 16 volts, Q3 is turned off. Then the PWD goes high level since the PWD is pulled up to VDD. When the CPU receives � High � signal of PWD, CPU goes to � Power failure process �. Note : During plug the Ac cord into outlet, all voltages are supplied to the PCB. If you open the machine for repair, make sure plug off. [Location for voltage check points] Actual value on the E259-1 PCB (unitV)
