Re: AMI JBM200 Tropicana question
by Dean Carriveau 11 Mar '24

11 Mar '24

Nygel, Tony, and John, Update, I've checked the CS3 Micro-switch as I manually turned the cam with an Allen wrench. Both the NC and NO terminals showed the internal contacts top open and close properly with my ohm meter at it's lowest setting. Very little or no resistance. The control relay "R" operates and released correctly when I turn the cam manually to start the transfer motor and it will load and play a record, then after playing will return the record to the carousel. so I believe the "R" control relay winding is okay. I would like to check the stopping micro-switch but don't have easy access to it with the search unit still in the machine. I'm a little apprehensive about removing the search unit to bench test the micro-switch and then throwing sequencing out of adjustment. Any tips for how I can accomplish that? Thanks for riding along with me on this misadventure. Dean On Sunday, March 10, 2024 at 01:37:19 PM PDT, Dean Carriveau <d.carriveau(a)att.net> wrote: Will do, NIgel. and thanks.

You can put a hex key into the cam pivot and turn the mechanism power off to check the positions of the cam microswitches when you reassemble them. Have fun.

Interestingly it is not mentioned in the troubleshooting for the previous years' JAL model, so I reckon it must have been a route fault reported. My advice with the microswitches is replace it with a quality one. Not a Chinese one. The tolerance between the NO and NC on this switch is crucial. I actually got in the habit of taking the original Cherry ones apart and cleaning them up, and a really slight bending of one of the contacts internally to reduce the gap and make it switch faster. What you may find is, you turn your jukebox on today and it works perfectly. Don't ask me why. But it will come back at some time.

Check the microswitch I mentioned in my previous email which is on the left hand cam assembly by the side of the rear of the tonearm. It requires removal of the mechanism. No others on that cam assembly will cause this problem. Check also the stopping switch itself on the rotating plate behind the search unit. There are 2 micros on there, one is the stopping switch the other is the a/b side switch. Check the wipers at the rear of this unit (5) and clean the tracks with deoxit. Check the detent solenoid microswitch right at the bottom middle of the mechanism in the middle of the frame by the sprag assembly. Check the Jones plug and nylon plug connections to the R relay. I said in my other email where it is. Your problem will likely be the cam switch micro. Bear in mind this was a rubbish design and although the mechanics of that mechanism were all identical up to 1976, the electronics concerning this issue were fiddled with and changed almost in a yearly basis, and improved upon. The problem is that the microswitch wears and/or the cam assembly gets a little sloppy, and it doesn't switch fast enough, and before it's switched and stopped the carousel motor and engaged the transfer motor, the pin has hopped. R relay is the symptom and not the problem. R transfers 28vac from the carousel motor to the transfer motor. I've spent 40 years owning a Tropicana and working on the 1100 mech and know exactly all the pinch points in this circuit. R also has a cap/resistor time delay on it.

Seeburg HFMA1 Amplifier draws excessive current
by M De Simone 10 Mar '24

10 Mar '24

I’m currently working on a V200 amplifier and can’t figure out where the current draw is coming from. I’ve isolated it to the 6.3 heater circuit but can’t find any issue with it. The only problem is the humidity adjustment is missing the wire wound section so it’s basically not doing anything. I put 2 resistors in place as a replacement but when I fire up the amp my amp meter starts rising and I shut it down between 2 and 3 amps. Usually when texting one of these amplifiers it slowly rises to about 1.5 amps and holds steady there. What am I missing here? Sent from my iPhone

AMI JBM200 Tropicana question
by Dean Carriveau 10 Mar '24

10 Mar '24

Hi all, My JBM200 Tropicana has gone from intermittently failing readout to now solid failure to readout and start the transfer circuit. Read in circuity is fine. The selected pin sets properly on the pin assembly. When the magazine motor starts and moves the magazine and stopping switch gear, the stopping switch finds the selected pin but jumps right over it without stopping and starting the transfer cycle. My manual shows that Control Relay R operates along with the shift solenoid through the stop switch when a pin is encountered. My question is: Where in the heck is control relay R? I've found R1, R2, and R5 but cannot find R. in the machine or the manual. Thanks, Dean

AMI G120

I have a customer with an AMI G120 that someone unplugged all the selector coils under the mech. Unfortunately, the manual doesn't show which plug goes where and I have two bundles of cables numbered between 1 and 12. Does anyone have a clue how they go? -- Paul Howlett Pinball Paul's 703-361-0420

Seeburg 100C Price?
by Tony Miklos 03 Mar '24

03 Mar '24

I've been looking for 100C's for sale to see what they are selling for but can't find any. I have one in the house that I'd like to sell and replace it with a Wurlitzer 1900 Centennial. I don't do a lot in sales so I don't know the price trends. Overall it looks pretty nice but in no way is it a *10*. Probably an 8. I got the Centennial and really like it so it's time for a new look in the living room. If you don't want to post here it's estimated value, feel free to email me direct. Thanks in advance, Tony

Schematics for Seeburg TSR4-L6 (not Code B)
by John Robertson 02 Mar '24

02 Mar '24

Does anyone have this schematic for the VH200 hideway Selection Receiver? All I have in my master manual is page 5145 which describes the Tormat Selection Receiver, but does not include the wiring diagram. Note this is NOT the TSR4-L6 (CODE B)! I have that schematic. If is not the same - missing the wiring for J16 - Pricing Unit Socket (12 pin). I ask because I am converting this back to a TSR3-L6 for a customers V200 and I couldn't find any TSR3s. It sure looks very close, but they made some modifications to the panel to not require the DPU1 (Dual Pricing Unit) and possibly other mods. I have TSR3-L6 and can figure out the difference in time, but schematics really speed up the process! I have most of the info for converting a TSR1-L6 machine to the TSR3-L6 (instructions 503860) at least. Thanks in advance if you have that schematic!

M100C Selection issue
by Jukebox Repairman 01 Mar '24

01 Mar '24

I’m trying to help a gent from a remote part of Canada with a selection issue. I’ve covered all possible aspects with him but can’t pinpoint the problem. Here is his story. I really need some help with my M100C if somebody could lend me some of your expertise. My M100C gets credits and removes credits with selections made but none of the pins in my pin bank move. My fuse is good, all proper group solenoids pull down with selections made, I can manually move pins and the mechanism will scan, pull record, play, return record and continue to next manually moved pin, BUT the selector buttons won't move the individual pins. The latch solenoid works and pulls the latch bar. I recently bought this machine and I've gone through cleaning contacts, adjusting contact points(as per the service manual but l've been unable to resolve
