Title: Help with Rowe R-87
Post by: Dream on October 20, 2009, 11:54:38 am

Hey guys, great looking forum here.. I'm new here and was hoping to post this question and generate some answers. If I’m off topic or in the wrong forum, please forgive and point me in the correct direction... here goes:

I recently discovered a co-worker has a Rowe R-87 that holds 100 45rpm's.

I powered it up, (I’m an engineer) and watched it work, however it's not working correctly, after a few hours of tinkering, resetting boards, reseating connections, even repairing a connector, and general cleaning of the inside, I'm still having an issue...

What is happening is, it appears as though it is not registering it's 0 position, the carousal just spins and spins, I would imagine that it would use it's optical scanner to find out where it's Zero point is, (guessing slot 100) but it's not stopping. it just spins.

Secondly, I have manually persuaded the arm to go and pull a 45 from the spinning rack, it stops, reaches in, grabs whatever 45 is at top, lays it on the turntable, the arm and needle come over, set down, then immediately raise back up, it picks the 45 back up, and puts it back in the carousal, then starts spinning again...

any suggestions as to what is going on with it?   

P.S., I have taken a few of the boards out and inspected them for cold soldier joints, but they all looked good.

Thanks in advance!!

First, you need the manual. It was included in that blue pouch attached to the amplifier compartment cover when the jukebox was bought new. If your manual is not there, then I suggest you buy one from the authorized & licensed source, www.victoryglass.com (http://www.victoryglass.com)

# 70-5764 (R-554) Rowe R-87 Field Service & Parts Manual, 135 pages, $39.95

Your optical switch assembly may have dirty optics or the optics may be bad requiring replacement of the entire optical switch assembly. Or it may be possible the mech control board has a problem.

Hi Dream,

Ken is correct you need the manual any from R-84 to R-88 will do for your purposes (power supply changed on R-86)
The opto switch adjustments need to be done at 99 which is the home position.

It could be a dirty opto or the gears teeth it senses. But you could have a problem with the Mechanism control or the CCC or just the opto switch.
One board most people avoid is the pricing board (rear of the jukebox near the amplifier compartment it has a clear plastic cover) this board is just a big connector and lines of data go through it, so check for cold joints (dry joints in the UK).
