Help with Moto schematics - pleeezz

[Keppie]

Hi all Moto fans from a long time lurker who learns from and enjoys all you AK'ers.
I would have put this into that long Motorola thread but I need your help with a specific console for which there is little info on AK and less on the web.
My Moto console is either a SK73, SK74, SK75 or SK76. Not sure which. It has a HS-963B amp (similar to HS-968) and a HS-964A pre amp ( 3X - X7's). Cabinet by Drexel; tt, but no radio. I found a schematic for the amp but as the schematic says, it is "very similar" to the HS-968. :scratch2:
Do any of you have a schematic you would be willing to share on either (or both) the HS-963 and the HS-964? Also, if you have more info, such as the parts layout and parts lists, my gratitude will be even greater.
Thanks and I look forward to any help.

It sounds like you (pretty much) have the schematic for the HS-963 but not the HS-964 tuner. The Sams folder is apparently 591-9, which should have all the parts ID; sorry I don't have a copy.

 

[Keppie]

OK! Thanks for the come back and a key piece of info! I didn't have the Sams folder #.
Hopefully someone out there either has that folder or knows where I might borrow or buy one.

Google will get a work out in a minute. LOL.

The pre-amp is also used in other Moto's. Calling all triple 12AX7 Moto pre-amps..where are you???

Did you know that you are missing a 6V6 tube?

 

[Keppie]

Sharp eyes, dude! I was in the process of vacuuming off the worst crud and pulled one of the 6V6's so I could get the area around the tube. Needed to take the pics so I could post 'em before finishing the clean up. Wondered if anybody was looking close. LOL.

Now I'm waiting to see if anyone has a SAMs 591-9.

 

[Tom Bavis]

As a matter of fact I do... and it's in the scanner right now. PM with an email address...

SAM's in hand

A huge thank you to Tom!

It turns out that that SAM's folder 591-9 contains everything I could have hoped for: schematics, under chassis pics with R and C's IDs, and detailed parts lists for the HS-963 amp and HS-964 pre-amp.

I will keep a good log of my restoration activities and pictures and post them when the project is complete.

Hey, Tom...can I have one, too? Pretty please?

 

[Funkeeuprght]

I have the same unit. How did you get at the pots like that? What must I do?

All Sams folders 1963 and before are public domain - copyrights have expired. Later ones have been renewed.

 

[Tom Bavis]

Sams never renewed their copyrights, so they expired after 28 years. The copyright law of 1992 made renewal automatic, and since 1964 and later folders had not expired at that time, those copyrights have remained in effect, and copyright expiration was extended again in 1998. Early Television Foundation, Radiomuseum.org, and many others publish Sams pre-'64 folders online. Sams sells pre-'64 folders for $7.99, due to competition. You can also buy scans from https:stevenjohnson.com, $3.99 and up.

Thanks again, Tom! I'm very excited, just waiting for parts to come in for the Voice of Music changer, then I'll post some videos!

I have had Sams scans on my website since 2004. I asked and received permission for one from 1964. Sams did contact me once; I sent them that email plus another from Sams COO stating that pre-'64 Sams were public domain. Haven't heard from them since.

Original term of copyright was 28 years, with 28 years extension if renewed (before expiration). But once a publication enters public domain, it can't be renewed. Thanks to Sonny Bono and Disney, current copyright terms have changed considerably.
