AMI Amplifier?
by Jamie McElroy 01 Aug '23

01 Aug '23

Hello all, I recently rebuilt my AMI G-80 amplifier. I replaced all the capacitors and Ive noticed that I am getting a little humming from my speaker and a little squelchy noise from time to time when my records play. Does anyone have any thoughts? Thanks as always Jamie

Seeburg Wall Box 3W1
by johngartman＠charter.net 28 Feb '23

28 Feb '23

Gentlemen, I have been on this list for a long long time, have 4 jukeboxes AMI-C, Wurlitzer 2700, and a Seeburg HF100R and an M100A. I have just picked up a 3W1 to hopefully hook up to my HF100R. Looking it over it looks like it only needs the glass dome and coin glass. Ordered from Victory Glass. I do not know much about Wall Boxes yet there is some information in my HF100R Manual. Some Questions for the Group. Looking for Gasket for the dome glass I see a set for sale for the 3WA 200 selection are they the same? I am a little confused on a Stepper? Or is that a Wurlitzer thing? Does the 3W1 just plug in to the selection receiver? I will get into the manual as soon as I have a little more time. Thanks for any help or advice you can share.

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 29 Jan '23

29 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 26 Jan '23

26 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.

Re: [Jukebox-list] AMI G sound quality with stereo records

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.

I have had AMI F and G jukes for a long time and no issues using the stereo compliant stylus with the original GE cartridge. There are some cartridge options if your cartridge is not original. Also you can plug in an external turntable to the amplifier for sound diagnosis.

I did purchase a new stylus from Needles for Jukeboxes and it was a .7 Mil needle. However it still does not play stereo records well at all. The volume and quality is far inferior compared to the 50's and 60's records. Thank you again.

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.

I have found some of these records do not play at the same audio strength as 50's and 60's records. Ami I doing something wrong or has anyone else noticed this with an older jukebox?
