Ok - now that proper oiling has been done (Thanks Rich!) Part 2 of the issues begin. I had it properly grabbing record, placing it down and tonearm landing in correct spot, (also amp turning on) - seeming correct start up sequence … Things have digressed a bit since then. (see below) vimeo.com/348645408above video shows the gripper arm grabbing record, but tonearm not landing in right spot, and also seeming not tracking (just floating) - also amp comes on just intermittently too. One last note is the activation of the gripper arm has been intermittent - only (roughly) one out of every three attempts activates start-up sequence. Feeling a bit defeated - any help/advice greatly appreciated. Greg PS I have also found a loose fuse with its screw-in installation cap - see below link. I can’t seem to find where it is missing from … the junction does has all four of its fuses … ? vimeo.com/348245081 |

Well, Greg
Who are you attempting to insult ?? Do you (being as young as you are) know what the daffination of "expert" iz---?
OK, I'll assume you don't, and tell you--"Ex" is a past --like an "EX" girlfriend--and a "spert" is just a little "drip"- !
On your tone arm problem--Just watch it--gottabe "hitting/touching" something (?) that's holding it up --
On that fuse-- that is, as I rit afore, a GMQ "safety fuse"--It is supposed to prevent you inserting a large fuse in that special holder--look for an open fuse holder marked, "3.2 ONLY"--or some such similar markings. Ron Rich

Well with that definition, we are all ex-spurts! Haha.
I’m not far from wheeling this beast to the curb.

While I don't have a machine like yours, one thing I noticed from your video is that it looks like the turntable slows way down at the point the tonearm should touch down, and speeds back up on the reject cycle. Not sure if the two are related as I don't know if the turntable motor would somehow be linked to the tonearm set down. I would still lean towards something binding or in need of some degreasing/relubing. If it worked a few times, I doubt that fuse you found has anything to do with it. May want to check it, could be a bad one a sloppy tech left in the machine after replacing it with a new one.

Tony,
The "turntable" (TT) ain't "slowing down" ! The TT is lacking the pad, or flocking, that grabs the record--the record is slipping on the TT.
If not corrected, this WILL, ruin records !! Ron Rich

Can’t figure this one out – whatever is hanging tonearm up is blocking it from being (manually) picked up and moved to the end of the record to reject. Also amp is not coming up. Tonearm just doesn’t seem “engaged” at all - just floats over record. See video. vimeo.com/348672185 |

Greg,
Do what I told you to do before- Didja oil it ? If not lift the REAR of the tone arm up, apply 20 wt. oil to the shaft Play a record--lift up the rear of the tone arm till you can swing the arm to the record--allow the rear to "fall down", set the needle on the record, and it will work ! Ron Rich

Thank you Ron! I took a good look at mechanism and it was indeed not seated correctly. so got it placed in the right way, but now I am back with initial problem still not solved. vimeo.com/347622144Selection picks and aligns correct record, but it stops without gripper arm delivering record. If I give the cam wheel a “goose” with an Allen wrench, the record is delivered, but it is not doing it automatically. Anyone have any idea why the motor the drives the cam wheel is not engaging when carousel (which is acting correctly) stops? |

Greg,
Gottom "da book" ? Read It-- I am not an expert--but if my mixed up, model memory-- I THINK it's the switch on the Sprague, that starts that motor-- It also may be that the motor is jamming ?? Check it for power at the time the basket stps at the selection---Ron Rich

I have all the manuals, including the all parts catalogs.
I have been reading like crazy, but they seemed to be geared more for maintenance and parts replacement (ala 1965) and not so much for issues that would be happening close to sixty years (some 70 plus) later.
Pretty sure no company thought their machines would still being used current day ... i.e. we’d have more sense than that haha.

Greg,
You GOTTA READ the schematics, and figure out where your transfer motor power comes from--then trouble shoot from there !
Didja read "Hi Newbies" in our FAQ's section-??-if not--please do so. Ron Rich

Yes, ploughing through schematics ... (still a noob, but learning) - the transfer motor you refer to is next to the cam plates, yes?

Yep Greg--that what the manual calls it ! I would have named it the "gripper motor", if I had been the AMi king !

Hi Greg,
Now back off of holiday.
With the 1000, 1100 and 1200 mechanisms you have to work your through the adjustments as per the manual, there are no short cuts.
My advice would be to first of all check out the power supply (named in the manual as the junction box) voltages, if the AC and DC voltages are too low this will compound any fault you have on the jukebox.
My next step would be to drop the transfer motor plate from the mechanism, this is the only way to check that the crank and pin assembly (part number 202-10807)this mall casting on the opposite end of the transfer motor shaft drives the transfer link (part number 200-10793) with the two pins that are fixed to the casting, the main pin that drives this is the longer of the two pins. The usual fault on here is the the rivet that holds the pin onto the casting becomes loose over the years. The result if this happens that all the adjustments you make to the tone arm cam and gripper bow can be correct at one time but out at other times. This is because instead of the operation of transfer link being a fluid motion it become an elliptical motion.
Get this correct and then start on all of your adjustments.
Ron and I have different thoughts with regards to lubrication, I would always request that end users do not touch any lubrication on the jukebox. I prefer to lubricate sparingly and only on specific points on the mechanism. A over lubricated mechanism will be easier to clean but certain parts will be worn out. A un-lubricated mechanism will be harder to clean up and may be rusty in places but would be more mechanically sound. Take for example the gripper bow assembly the only lubrication on this should be high melting point grease in the two pivot point holes in each end of the casting, if you oil the trunnion gear or cam gear the operation would be quieter but the oil would heat up and distort usually the trunnion gear.
Please let us know how you get on and if you need advice or spare parts.
Regards
Alan
