Row-Ami R87 selection problem

[CHRIS-F]

Hi Guys,

My Dad's jukebox has a small problem, It's a Rowe Ami R87. Most of the time it works as it should but occasionally when you make a selection the display says the right selection but it will play the next song, for example if I select 100 it will show 100 and play 101 if I select 127 it shows 127 but plays 128. I have recently repaired both his main board and a spare main board which had corrosion due to battery leakage and I replaced some caps, both boards seem to be working fine, but the problem is there with both boards. Am I right in thinking it is more a mechanical issue?

Regards,
Chris.

Hello Chris-F,

Welcome to the forum.

Have you checked your opto switch adjustments?

Have you cleaned the opto switch and the gear that passes through the switch, if there is a build up of dirt it effects the opto switch.

It would be as well to remove the Sprag Assembly and check the sprag wheel for any damage to the teeth on the gear and the stem bushing (the rubber grommets) for rotting, if they are rotted this allows for excessive play on the basket, check this by rocking the basket from side to side.

Thanks Alan,

I'll take a look at the switch this weekend, how complex is the sprag assembly to remove and check? do you have to remove the whole carousel etc to get at it? I do have an R87 manual but haven't read through it yet.

Thanks again,
Chris.

Hello Chris,

The best option is to remove all the records first.
Put the service switch into service and press the cancel button near to tone arm, this turns the mechanism around to remove the records.

Turn off the power and remove the complete mechanism/carousel after removing the cables to the phono input, the plug that goes into the mechanism control into P205 and the molex plug that goes into the socket on the left hand side of the mechanism frame.

Once the mechanism is out of the jukebox, lay it on its back and remove the mechanism control board after taking out the plugs NOTE always pull any plugs out by pulling on the plastic plugs rather than the cables.

If your mechanism has a metal mounting plate behind the mechanism control, this will also need removing.
The machine screws are 4BA or 1/4AF.

You will see the sprag assembly is held on with 3 of the above machine screws, remove the cables that go to the motor and the sprag coil (called solenoid assembly in the manual).
With the cables removed, remove the three screws (they usually have washers on them).
The motor will be able to be removed by sliding it to the right hand side it is a tight fit but it will pass behind the right hand side pillar.

Once the sprag assemby is out you can inspect the sprag wheel and stem bushing which is on the rear of the assembly, hence the reason for its removal.

The above carried out by an engineer takes minutes to perform.

Please lt us know how you get on.

Thanks Alan, we did this with the spare carousel just to get a feel for it, and then I noticed a couple of things when we looked at the jukebox, the opto switch adjustment was missing it was just a bolt holding it in place and secondly the opto switch had grease in it and there is grease around the toothed wheel, I assume the grease is not meant to be there? We cleaned the inside of the opto switch and put the switch adjuster off the spare mechanism on, adjusted it as per the manual till the index light just goes out and then fastened the bolt in place, fired it up and all seems to be working fine at the moment, selected about 20 records and they all selected properly, I'm hoping it's cured the problem but to be honest this seemed to be an intermittent fault, will see how it goes, just out of curiosity what do the index and home pots do on the board?

Also Alan do you sell extension speakers? if not do you know where we can get any? my dad wants to put a speaker or two in the kitchen, I've spoken to you before, I think you said the amp looks like it has been used with a wall box and extra speakers before, but I'll cross that bridge when we come to it.

Thanks again for your help much appreciated.,
Chris

Hello Chris,

If your mechanism control has index and home pots then the mechanism control must be a 4-07221-05,

This board was ment to be used on the R-89 to R-94 and used in conjunction with the opto switch with the red plug on it rather than the white plugged opto used on the 1979 CTI-2 to R-88.

I a kitchen you may be better using ceiling speakers, I have one in my kitchen at home, you have got to have music whilst cooking/prep.

Are you in the UK?

Hi Alan,

I checked the jukebox before the board I was looking at was indeed a 4-0722100-5 mechanism control it was out of a hideaway R89 my dad bought spare for the carousel, I double checked the Mech control board on his R87 just to make sure and that is a 4-07221-02, I assume that's the correct one?

Yes were in the uk.

My dad (Maurice) has had a few parts from you before, he's after some orange number buttons if you have any see pics below, can any speaker be used, I remember reading in the manual 8 Ohm or 4 Ohm or something can any speaker be used if the Ohms are right?

Regards,
Chris.

Hello Chris,

Is your Dad Maurice Flynn?

Any speakers can be used but I would tend to stick to 8 ohm.

The only number buttons I can offer your Dad would be solid orange with white numbers or solid white with black numbers or solid black with white numbers.

The Mechanism Control number is correct for the CTI-2 to R-88.

Alan

Hi Alan,

Yes that's the same Maurice, he's looking for the translucent orange buttons as in the picture with the black numbers, he's had a set of the other orange/white ones but they don't look right on his, if you come across the ones like the picture at some point please give us a shout.

Thanks again,
Chris.
