Repair Log for the Rock-Ola 446 and Seeburg Entertainer I got from Slither

Postby mrmikeman » Wed Aug 07, 2019 8:59 am

So thanks to Slither I am back in the hobby after a 10 year break! Been back only for just over a week and already loving it and realizing how much I missed it :)
viewtopic.php?f=48&t=25532

After reading some repair logs posted here about pins I realized I suck! The Rock-Ola was definitely very interesting in getting running and I should have taken pictures but I was too intellectually stimulated to even think about it. I had never worked on or even seen a Rock-Ola! I owned a Seeburg LS1 for a while and worked on a Wurlitzer (I think) for Shoeguy. First thing was to get the parts manual (good for assembly diagrams) and service manual (schematics & theory of operation) for both. I recommend theboneyardpdflibrary.com. $35USD for 1 year access to pretty much any jukebox material you can think of. Was cheaper than buying reprints.

Rock-Ola 446
Repairs done:
- Complete mech assembly had been removed from machine at some point I am guessing and all springs and hold-down bolts were removed. Luckily found them in the machine. Re-installed.
- Gripper mech had been disassembled and then re-assembled improperly and mechanically jammed. Re-assembled properly and aligned. Took a while to get it right.
- Rear cam (with the 4 micro-switches) was loose and mis-aligned. This one also took a few tries to get it right, even with the service manual.
- Gripper motor was non-working from over-heating on a jammed mech (from the incorrect assembly mentioned above). Twas all gunked up inside, 1 brush was broken. Cleaned/lubricated armature/bushings/bearings and re-soldered the brush wire to the brass contact tab. My favourite ingenious fix by far lol.
- Most wiper switches on write-in and read-out wheels were not working/making contact. Lots of contact cleaner was used here but NO abrasive materials!!
- Write-in process was not working. Relay in credit unit was not making any sound. Opened it up. Credit unit was packed with pink insulation and a dead mouse. Once cleaned it worked.
- Alignment with magazine and gripper arm was a little off. Better now but not quite as good as I want it. Will get back to it.
- Sound was only coming out of 1 side (stereo) but both sides in mono. That narrowed the problem to the input side of the amp circuit. Took a while to find the culprit. Pickup switch (magnetic/ceramic selector) was dirty. Contact cleaner to the rescue again.

So now the machine works as it should but still needs TLC with:
- I have buzzing that builds up and gets loud during play. Tapping the machine makes it go away most of the time. I have new capacitors for the amp to see if it will help. I suspect it's static electricity that builds up on the tone arm. Grounding it to the chassis makes it worse though. Making a song selection (using the write-in system) while a record is playing makes a deafening noise. The write-in motor is creating electrical interference/noise in the amp circuit. I was thinking power supply caps(dried up electrolytic caps) but there are none(electrolytic)! If the amp cap kit doesn't fix I am somewhat stumped. Will also re-check the pick-up grounding strap to the amp. It's a bit rusted and may not be making electrical contact.
- Needs a few #53 bulbs for the "Now Playing" display, which is off by 1 anyway so I need to align that on the mech.
- Drill the coin box lock. I can see another mouse nest in there.
- Cleaning the exterior!!! Need to really clean this thing. Am thinking of soaking (only for a few minutes) the front board with the speaker cloth in warm water/oxy-clean. Obviously with all speakers and wiring removed. Then need to clean the glass on both sides.
- Whiten the yellowed plastics. This includes the title strip holders and the front speaker panel illumination plastic. Not sure about this one yet. Yes I have read all the "tricks" online just not sure how I will proceed yet. It's all pretty brittle.
- Need to re-glue the Rock-Ola emblem and model number plates. I have them but they are loose.

Then hopefully sell it to fund the repair of the Seeburg, which is the one I'd like to keep.

Seeburg STD2 Entertainer
Repairs done:
- Write-in and read-out circuits cleaned and now functioning. Picks-up, plays, and returns records to the magazine.

Remaining issues (so far):
- Some broken/loose wiring in there. It's been hacked somewhat. Need to repair/clean that mess up.
- No sound. Hooked up the seeburg mech/player to another amp and no sound. Hooked up a real turntable to the seeburg amp and no sound either. Bummer.
- Heatsink for right side on amp gets burning to the touch when powered on. Probably shorted transistor(s). Seems pretty common on these things. So the amp needs a cap kit, new components to replace the blown ones that I need to identify, and new PCB supports as they are broken and the 2 boards (pre-amp & driver) are loose in the amp.
- 1 main speaker has a hole in it (mouse ate it's way through it). So I need a 12" speaker. Might as well get 2 to keep them the same.
- Burnt #53 bulbs in the selection/now playing control center.
- 70% of the chaser lights not working. Either burnt bulbs (2182D) or shitty wiring (they used IDC for this) or both.
- Chaser lights not "chasing". 5-bit controller not working as it should.
- Strip and repaint(spray gun) the black parts of the exterior. Someone painted it with a brush and you can see the brush strokes. Annoys me.
- The shiny metal parts have a little bit of surface rust so need to buff that out.
- Clean it (especially the infinity lighting and front speaker grill).
- The back panel and coin door were missing but Slither found them so I will get them soon! WOOT! :D

That's it so far!

Pins coming in the near future.... ;)

Welcome back Mike.
Those juke repairs are impressive, Well done, sir.
And, these things are usually quite heavy!

If you have a chance later, I think many people would probably appreciate pics of your jukes,
including some showing the insides such as the carrousel, gripper, selector pins, assemblies, speakers, amp, etc.
I suspect quite a few here might never have seen the inside of a jukebox...

Good luck for your upcoming pins!
Cheers,
-Sylvain.

Yes, please! Great thread but some of us are 'visual learners'. :oops:

That Seeburg STD2 Entertainer is gorgeous. Good luck!

... and very nice of Slither/James. Generous yet again. *double-thumbs up*

Will take pics this weekend. Really too bad I didn't do that while fixing, especially that "burnt" motor. Saved quite a few $$$ by repairing instead of replacing. I will definitely take pics of the Seeburg repair once I get to it. Getting my "first" pin on Saturday and it's not booting up(WPC) so that'll be my focus til I get it up and running. :)

Cheers,

I have pics of where I am at. And 2 videos showing a 45 rpm and the auto speed adjusting for a 33 1/3 rpm.

You will notice the buzzing and also the need for lubrication in the mech. I cancelled the plays btw. They didn’t just stop playing lol.

No prob. I will get better pics of the areas I worked on once I get into the cleaning. Also received my gopro head mount yesterday. Just easier than stopping and starting all the time to take pics.. (I think.. We'll see how that works out).

So replaced all the caps on the amp. The size difference on some is hilarious. The 2 main ones were the size of D-Cells. The replacements about half the size of a AA. lol.

However my buzzing problem remains somewhat. When it starts playing a record, I think there's a magnetic field that builds up on the tone arm/needle. Gets super loud and then gone. The rest of the record plays without any buzzing. Next record comes on, same thing. More research is needed!!

Pics aren't in order. First one shows after chassis and first board done working on last one. Second picture shows the before look. I wanted a visual reference for polarity, forgetting that it's in the service manual..
