Checked transistors and diodes on preamp board.
Replaced right side transistors and fuses. (stock speakers, no addon's)įound a broken leg on a cap on the crossover for the high end, replaced. I would not expect that to make a difference, but maybe it does?ġ00C 250 watt amp with blown right channel.
#ROWE AMI CD JUKEBOX MANUAL#
I am using 100uf 50v cap which is shown in the manual vs 50uf 25v original. I ve replaced the three dioeds with white print with 1a 100v and the three blue with 3a 400volt. In addition, the original unit had different capacitor and resitor then the manual. If anyone can clarify this or provide a detailed description of how the magazine detent/switch are triggerd that will help. I beleive from left to right the wires on this tab are w/y, w/v, b, not sure if there are any wires connedcted to the last tab which seems to the resitor from the relay, the positve end of diode 2, and maybe the resistor that leads to the w/v wire at solder tab 2. Unfortunately, I cannot see connections under the capacitor or the wires and connections on the solder tab with diode 2 and the resitors. Does anyone have a good picture of the relay wiring? I borrowed this picture from a different post which seems to be the same as how mine was wired. I'm guessing the problem lies in the wiring of the relay which is not allowing the magazine detent and coil to power down.
CS2 seems to work fine testing with ohmeter. Pin 14 is connected to the capacitor which leads to pin 4. DIode 2 feeds the W/V wires which go to pin 14 of the relay, the hub switch, and CS2. The stop switch appears to work as I get a momentary spike in voltage at the negative end of diode 2 (yellow wire from sweeper ). It is now not stopping at all and the magazine continues to rotate. As before the credit unit works, the search unit works, but the stop switch jumps over the pin. I tried to back into the wiring by following the operations section. I've attached a pic of the schematic with a circle around the tab showing the two w/y wires connecting. I'm trying to match the circuit process diagrams to the schematic but it's tough as wire colors are different between the two sections of the manuals. So if anyone has an updated schematic or can provide a detailed description of the harness plug, relay, and diode set-up, I'd appreciate it. Seems like there is no way for it to complete a circuit as wired. I have wired in accordance to the schematic and the stop switch is not working. However the schematic shows a W wire from the relay and a W wire going to CS5 on tab 4 where diode2 starts. The step by step circuit diagrams show the w/y wire connecting to diode 2 on tab 4. The schematic shows the w/y wire comin from pin 8 of the harness (which has no lead attached to the harness side of the plug) going to tab 3 of the middle solder tab where it connects to the w/y wire that goes to the slip wiper on the stop switch. My manual does not seem to have the correct wiring for the harness, relay and diodes. that has all 3 of the main boards ck'd out and I ordered them from him waiting.I picked up a Rowe MM5 and am having problems with the record changer wiring. Several weeks have passed, and now I've found a fellow in Cal. When he left, he said his shop had bought out someone down in KY and there were a lot of parts for these old AMIs and he'd ck. He was trying to remember from the past, but ended up taking the board with him and had someone look at it and they replaced some of the transistors and couple of resistors that were burnt? Upon coming back, replaced the board, plugged everything in, and when powered up, the carousel kept jerking and sounded like a solenoid kicking on and off and on and off till that memory board started smoking and he switched it off. I've got the service manual on it, but called around and found an "older" gentleman who USED to work on these years ago who came to work on it, and after unplugging and pulling different boards out and looking at them, thought it was the memory board. Now, I SHOULD have known better, BUT, the folks helped load it up laying it down on it's back! My stupidity, I know, once we got it about 5 miles to my brothers, of course, no play now! Lights up, but nothing else. I purchased for my brother who's wanted an old 45 jukebox for years! Bought an R83 that played just a single record in their garage when we looked at it, and the carousel didn't move upon powering up, just pulled the record out, played it w/good sound, and then replaced it back and then pulled it out again and played the same one again.
