Other parts to check via Ron was secure clamping of the record. Clamp arm spring and center pin entering TT with no resistance when clamping record. Motor coupler and oiling motor with his favorite ND 20 wt oil thru all of the drive train. It didn’t have a motor support plug but added one. I would at least check the bearing for no flat spots and screw condition even if u have no play In TT. Kent Sent from Mail<https://go.microsoft.com/fwlink/?LinkId=550986> for Windows

A quick update thank you Rob for the detailed instructions very helpful. I replaced the Cartridge with the NOS one from eBay it sounds fantastic! I did replace the Sapphire needle that came with the cart it for a new diamond needle. I did have to make a small adjustment to the trip switch but other than that good to go. This was for an elderly couple both in their 80’s and they were thrilled to hear it playing again.

2 yrs ago I worked on my neighbors USC-1. His band The Mystics had a hit song “Hushabye” . After recapping this juke his record sounded terrible (wavering). Other records not as noticeable. With Ron R’s help I tried many fixes. Nothing helped until he said try to see if the TT thrust is correct with .003” play. Mine had at least 1/8” and would not adj with thrust screw adj. The adj screw was hollowed out on the end from wear. Replacing screw and adj fixed the wavering problem. I had to buy 25 screws, so if anyone needs 1 let me know.

Selection Issue On TSU5 After Replacing TJU with RCSU
by Jerold Kress 28 Jan '23

28 Jan '23

Issue: The mechanism picks up and plays the first record (R8) no matter what selection is made. Also, while scanning and a selection is made, the mechanism immediately plays what ever record it's near. The jukebox was selecting fine. The issue appeared after I replaced the TJU3 with a RCSU3 and hooked up a wallbox. Using the wallbox to select a record exhibited the above issue. I then reversed my work, replacing the RSCU3 with the original TJU3 but the jukebox continues to exhibit the selection issue described above. I re-seated all the connectors with no improvement. I figured something happened when I replaced the TJU3 with the RCSU3 but have yet to figure it out. I have the manual and can start the trouble shooting guides but was hoping someone could deduce what happened between hooking up the RCSU and then reinstalling the original TJU3 in the TSU5. (Previous fix: replaced both AO2s, 6X4, 6X4 socket, C515, C514, R518). Thanks for any insight! jerold k

This machine is mine and although it's in nice condition, they are so ugly I might have to part it out. It got put aside but I have limited space for other machines in the shop so I'd like to sell it/get rid of it. I can't sell it with the warble. Any clues yet as to what is causing this? I didn't try changing the motor cap since it does it on only one side.

Replacement Caps In Seeburg RCSU3
by Jerold Kress 25 Jan '23

25 Jan '23

I’m about replace a couple original electrolytic caps in a Seeburg RCSU3 before hooking it up for the first time. Two of the caps are 25uf/50V. I have either 22uf/50V or 33uf/50V. Any suggestions of which would be a better replacement or should I seek out 25uf’s. Thanks.

I am pretty sure the cartridge you have was used on the G200 and newer like H and I models. Not sure. I don't have those models or manuals for them. You would have to research that. F80 F120 and G80 G120 would use the GE RPX - 040 style. Thats the one I see in them and use. You need to diagnose your problem before wasting money on cartridges. Even the one you are using should make no difference and sound good. You need to check what I have listed at minimum. A good cartridge option is Shure M77 series. It will fit with minimal modifications. Don't solder the tonearm cable to the cartridge. use some adapters. Again, diagnose the problem first.

If you do then you probably had a 1 mil stylus in there designed to play mono records. The size of the needle fits the size of the groove on mono records of the 50's and some early 60's records. If you replaced with the same one then that would explain why there is no change. Using a 1 mil stylus on stereo records of the early 60's and newer will damage the records. Stereo records are designed to be used with a .7 mil stylus that fits the groove. Using a 1 mil mono needles on stereo records will plow out the records grooves and cause damage. Alternatively using a .7 mil stereo stylus you can play mono and stereo records. I use a .7 mil stylus in my AMI F and G and it works well. Needles for jukeboxes sells the stereo .7 mil needle.

Hi Jamie, Back to my original reply to you. I dont think you have a problem, unless the output of more modern records is seriously quiet that it's totally obvious. That is the way the records were made, coupled with your old cartridge, and the fact your machine doesn't have AVC to level the output of different records. I would advise upgrading your cartridge regardless. Shure M44C or Stanton 500, Stanton 400V3 or Pickering NP/AC.

Rock Ola accu trac arm pivot friction
by Nigel Pugh 22 Jan '23

22 Jan '23

Can anyone tell me please is there a bearing in the bottom of the brass tone arm pivot ? I cant tell with a torch if it's actually a bearing or an indent ? The reason I ask is, I have 3 of these arms and each one seems to have the same problem, there is too much horizontal friction in that bearing and the stylus cantilever is pulling the arm, so when you watch it close up it looks like the cantilever is doing a little dance to the let and right. I'm experienced in tonearm setup and have ruled out everything other than friction in that shaft. 1. Pivot shaft flushed clean with IPA and lighter fuel, spotless 2. Tonearm cable removed completely 3. Trip switch removed 4. Tracking set with digital guage between 2 and 7 grams (Shure M44MR original cartridge) 5. This issue usually occurs when attempting to track a cartridge at the lighter end of it's spec, or with stiff tonearm cable 6. If I track at 7 grams it's ok, but that's definitely not right. Should be 3 to 5. 7. Tried with kiddie spring and also counterbalance 8. Used various new and used styli, M44C and domestic M44-7 I've got 7 jukeboxes and 8 turntables and by a long shot this arm has infinitely more friction than all of them. And all 3 variants of this arm do also, hence asking if there is or should be a bearing in the pivot. Or, is it just a really bad design ? Any ideas ? I've had this 470 for around 30 years and only discovered this when I realised the crappy arm spring had stretched over time and was tracking on the lightest setting at 7g. So I made a counterbalance and that's how it's come to light that the arm don't like tracking below 7g. It also sounds much better at 7g. Something isn't right so I'm looking for an outside of the box thought or a sensible modification. Maybe there's nothing wrong at all and it's just a rubbish design. I did think about dropping a bearing into the shaft but haven't got one to hand. Nigel, uk
