Any luck with PDF of schematic or manual as I could use a manual myself.Thanks

That makes three of us! Hard to believe there isn't one out there!

I found a manual if someone still needs it scanned. No schematic though.

Hi all,
I'm looking for the Hayburner II score motor part number. A friend of mine has a 35 RPM score motor in his Hayburner II and usually, Williams from that area have 14A-7806 (28 RPM).
If a pdf manual is available, I'm interested...

This is from the 1969 Williams parts catalog available at Planetary Pinball's site.

Part number is 14A-7805 for the 60 Hz motor.

Thanks, that’s what I did. I got the part nb 14A-7806 for a 50 cycle motors we have here in France from the 1969 Williams Part catalog from Planetary Pinball's web site. This 14A-7806 motor is rated 28 RPM.
My friend’s Hayburners II is equipped with a 35 RPM score motor. I was wondering if this reference is specific to that model or if it has been mounted by error in the pinball.

You might ask in the EM pinball section- https://pinside.com/pinball/forum/forum/tech-em

The US uses 60 Hz, Europe uses 50 Hz. If you use a 7805 on 50 Hz it will turn slower. If you use a 7806 on 60 Hz it will turn faster. I don't know the 'normal' RPM but I bet the EM people would know.
