ami-man's advice on Rowe Ami jukeboxes

Hello Patrick,

Welcome to the forum.

John is quite correct with regards to the wiring on the output package both for the volume connections and the how to connect up the phono speakers for there maximum output.
The pink and violet phon speaker cables are set to E3 left and right which would have been set for a lower sound, it could be that extension speakers were connected at an higher tapping on the output package.

Im having trouble with my TI-1. When I first got it the jukebox wouldnt play certain selections. Like if I chose C3 it would play any other C # but 3. However it played every other selection I chose flawlessly. After about a year of use it started to do the same thing on multiple selections. I thought the Selector board was getting dirty so I tried cleaning it with Brasso. After that it wouldnt work at all. No matter what selection the jukebox would keep searching endlessly. I tried taking the whiper off and cleaning that and the board with a pencil eraser to get the polish off and it still didnt work. I found new PCB's online how hard is it to change it? I had the manual but it didnt seem to make sence to me. I am a very handy guy and was an auto mechanic for 15 years so Im fairly certain I can do this. I just need a little help.

Hello roweti1,

I guess you did not read my posts about cleaning and lubrication on the search unit.

Regarding new pcb's for the search unit on Ebay there is two sellers one in the USA and the other is in Tasmania, I also have a few.

These pcb's were made with a special process where the tracks are compressed into the board, so to the touch the tracks should be flush to the board, if you buy one and it can be felt above the board these have only have been etched and would last less than 6 months. A number of companies tried doing than in the 1980's.

You need to place the seach unit in the position that it would be selecting A1, there is a mark on the front of the pcb with an arrow showing No1 ADJ. This mark is the A1 timing mark (this is all shown in your manual and how to adjust the wipers to this mark).

Remove the spade connections off of the front wiper assembly, undo the machine screw that locks the assembly to the shaft, and pull the assembly off of the shaft. Remove the four 4ba (1/4 AF) screws that hold the pcb in place and pull the pcb off of the shaft.

I suggest that you clean the S1 & S2 open relay contacts with a taper made from paper pulled through the open and closed contacts.

Do not use any spray, WD40, sand paper etc to clean anything on a Rowe Ami jukebox of this era.

Rebuild the search unit as you took it apart and pay attention to the picture in the manual regarding how far to push the wiper assemby back onto the shaft, the contact pressure needs to be correct.

If this is beyond what you can successfully  achieve by all means send the parts to me for installation & testing.

Alan

Thanks you for your reply Alan. The way you explain it makes a lot More sence than the manual. I just had 2 questions should I clean the wiper at all? Also does the jukebox have to be set on anything specific before the wiper is set to A1?

SO I got home and started checking a few things on the machine. I got curious and I took the plugs off my Board and got my meter. I set it to continuity and I put one lead on each wire coming from the wiper and the other lead where each plug would sit on the board. Then I spun the little wheel that the motor turns. I had continuity all the way around. Is it possible my Board is still ok? I did check what you told me and sure enough each trace on the board is slightly raised. However it still has the part # L-5048. SO next I tried to line the wiper up like you told me but I couldn't find the mark on the board. So I did some digging and found my manual. First I checked the rear wiper by rotating the sprag wheel until the hole was showing then I locked the S2 relay into it, the inside wiper pointed to the JK mark like it was supposed to. Then it said bottom the S1 relay into the Sprag notch. I had to turn it a little counter clockwise to get the relay into the notch. However the short select coil arm wasn't facing up and down yet so I turned it a little more until the coil was facing the 12 and 6 o clock positions. then I set the outside wiper to the bottom left notch like the manual says. then I turned the machine back on and punched in a song. The machine just kept seeking and seeking. Then I tried pushing the S1 relay arm down and it would pick a song the letter portion would be right but not the number. An example would be if I pushed k3 I could get K 1-9. Could it be coincidence that after I cleaned the board something else happened to fail? Am I adjusting it wrong? Heres the directions I was using.....
