Hello all. I have a Rockola Bubbler CD8C and when it is turned on, it give a ERROR message in the display. it says DIAGNOSTICS MODE CD Comm. Failure. Where do I start? Does anyone think it is possible that the board inside the CD PRO Player went bad? Hoping for some experienced folks to point me in the right direction. Thanks,Ron B

This amp will play for about 2-3 minutes then blows the 2 amp fuse. Tubes all test good. I’m confused.

ROCKOLA MODEL 496
by Ron Medlin 02 Oct '23

02 Oct '23

Hi All, I have Rockola Model 496 with the System 3 Control Unit 55130-A with an intermittent problem. After power up, the machine will generally play a single selection correctly as per request. Generally, after playing the initial selection, it will not accept further selections. After power off, and several minutes wait time, it will repeat the same process. On one occasion, the machine attempted to play all selections in the carousel, after pushing several numbers on the keypad. I suspect a problem with the System 3 Control Unit, but I don't know where to start. Any tips? Ron Medlin 11815 E. 58th St. Kansas City, MO 64133 Home (816) 326-7399 Mobile (816) 419-7000

STD-4 Trip Problem
by Jim McClave 02 Oct '23

02 Oct '23

Mechanism trips continually as soon as a record is placed on the turntable. I read a short to ground across the trip switch on the mechanism continually. Disconnected the 6-pin plug on the amplifier and short still exists. Looks like the short is somewhere in the mechanism. Any ideas?

Does anyone recall how many ohms resistance the trip relay coil should read? It is the little red "cube" type relay. Installed in the dcc4 control center. Im reading about 700 Ohms. Jim

Seeburg AY100, record is in play and when you make any additional selection it causes the mech to trip to scan ?? I’ve never encountered this before. Any ideas?

New Amp issue. Seeburg MRA1-L6

This amp had been recapped awhile back and working properly. Owner said he went to play, powered on and a very loud hum then blew the fuse. He replaced with same value and same thing happened. Should I be looking for a shorted tube, open resistor?

Rowe CD 100 transfer motor
by Paul Howlett 28 Sep '23

I have a customer that has a CD100 that the transfer motor runs continuously. I have replaced the mech control computer (6108602) and tested the cam switches. If I stop the motor manually at a selected CD it will play the CD. The optical switches are working. The scan/transfer LED is constantly on. The board error LED is on intermittantly. -- Paul Howlett Pinball Paul's 703-361-0420

Seeburg MRA1-L6 AMP question
by Jukebox Repairman 28 Sep '23

28 Sep '23

I just finished installing a replacement cap kit in the above-mentioned amp. It is being used in a M100C. Using a redhead cartridge (with good needles) I'm finding the output of the amp is poor. Even with the volume maxed the output is nominal. I tested the tubes and the 6V6 drivers only read in the 50 percent range. A couple were 51 -52 but still low. Do you think a fresh set of tubes will increase the output? Regards, Rick

Seeburg V200 Does not pick up B sides (right side) records
by M De Simone 20 Sep '23

20 Sep '23

Hey All, A jukebox hobby friend asked for my help as he really doesn’t have computer savvy. He has a V200 with a TSR1 selection receiver. When he performs the battery trick all selections are selected and played. Making a selection from the keyboard works fine for all A (left side) selections but the mech will scan twice and not pick up any B side (right side) selections? He has tried swapping the 2D21 tubes and has traced out and verified all the wiring is good with continuity. To me it sounded like a readout problem at first but the fact that it selects and plays all selections when charged by a battery kinda eliminates a readout or trip.problem and the fact that it selects and plays A sides, I think, rules out a write in problem? I was hoping someone could offer some suggestions as I’m really not good at remote troubleshooting and this seems like a very odd problem to me. Much appreciated, Mauro Sent from my iPhone
