Rockola princess deluxe 435 mech issue
by angus maiden 20 Dec '25

20 Dec '25

Hi all I hope everyone is enjoying their xmas records on their jukeboxes! I have a Rockola princess deluxe that has worked perfectly for the last 25 years, but now the mech magazine no longer rotates after I select a record. However, the magazine mech does rotates perfectly when I move the service switch from the "oper." position to "scan" position. I cleaned the contacts on the service switch, but that did not fix the issue. Sequence 2 in the manual seems to indicate that the problem could be the "play control relay" and related contacts, as this appears to operate the mech magazine, turntable motor, and amplifier. Can someone please tell me where this relay is so I can clean its contacts? I'd also appreciate any other tips on what could be causing the problem if it is not the relay. Thanks, all! David

Antique Apparatus speaker wiring?
by Tony Miklos 11 Dec '25

11 Dec '25

I have this in the shop and don't know how the factory speaker wiring was (it's all mixed up now). It has a stereo amp but only 1 woofer, 1 mid-range, and 1 tweeter. I forgot to look at the cartridge to see if the one channel is reversed like the early stereo ones. These didn't come with their own manual, only an R-91 manual which of course has left and right speakers. Also, from the factory they spliced different speaker wire around to it's hard to follow. If someone has one of these, I'd love to know what speaker wires go where (from the factory anyway) -- Tony Miklos Tony's Jukebox Repair

Jukebox Wiring

Tony, This will be redundant. I responded to the thread but it was held up due to size. I was mistaken. My sister's jukebox has one woofer but two midrange and two tweeters. Has the standard Rowe crossover and transformer/speaker tap assy. I still took pictures if you want them Karl

Seeburg SE100 Golden Jet

This juke doesn’t trip at end of record. Owner doesn’t have a manual and I don’t either. Can someone tell me if this trip circuit is fused or ??? I have to drive 2 hrs one way so I want to be able to correct in one visit. I remember once the magnet came off the base of the Tonearm on an S100 ( they were glued on) But owner says magnet is still in place He says it won’t trip via the reject switch either. Regards Rick

SHP3 Amp
by ROBERT wilson 03 Dec '25

03 Dec '25

Hello All, I have a SHP3 amp, when either RCA plug ( Input ) is disconnected, both channels play still play. If I remove the mute relay the sound level drops but does not quit. I have checked for shorts in the wiring, shorts on the boards, checked the diodes. I believe the problem is in the preamp section. Can someone point me in the right direction?? Thanks Robert

Output Transformer for Wurlitzer model 503 amplifier from 1015
by M De Simone 03 Dec '25

03 Dec '25

I have an amplifier to repair from a W1015 and it requires an output transformer. My usual Hammond “go to” replacements will be too tall as this one is mounted underneath the chassis. Just wondering what others use here? Preferably Hammond as I’m in Canada. Thanks, Mauro Sent from my iPhone

Wurlitzer 616 Questions
by dvachon3＠teksavvy.com 21 Nov '25

21 Nov '25

Hi, I've had this Wirlitzer 616 for many years and have it torn down for the fourth time. It would work good for a few years and then 2 trays would come out, the turntable would come up and jam and shred the 5" main fiber gear. I would like to do this right this time. My questions are; Is the bushings for the mech available? Has anyone ever seen or used the 5" metal gear that occasionally comes up on ebay? Thanks. Doug

Wurlitzer CD Computer board
by Tony Miklos 18 Nov '25

18 Nov '25

I have a customer who swears his OMT was brand new when he bought it. Someone else before me upgraded it to a CD Pro when the older ones stopped working. I temporarily lost the serial number, but it fell within the range where all the BC 337s needed replacement. Looking at the credit/control board... it appears that all of the transistors were replaced, including the BC327s. Or who knows, maybe they were all removed, tested, and replaced with the old ones? I can tell by the soldering and the rosin that they had been soldered in again. Anyway, it won't play a CD. It looks like the usual bad CD player problems, in and out, spinning erratically then returning it to the carousel. A good working player acts the same way, and the player from it works fine in my test box. So should I assume someone did indeed "test" the BC337s and put them back in? I have plenty of 2N2222s to replace the BC337s. To make things worse, I don't have a Wurlitzer to test it in, and it's a little over an hour away to the customer's house. Any ideas? Words of wisdom? Change the transistors and take a trip there? - Tony Miklos Tony's Jukebox Repair

SMC2 mech problem/ Ron Rich Gen2 MPU
by Kent Z 03 Nov '25

03 Nov '25

My sons SMC2 was recently moved. It has Ron's GEN2 mpu. I have RTFM and Ron was adamant about making sure the carry over switches are open and never close on the 2 Limit switches that control the reversing the mech at end of travel L/R. or the mech will have motor run on and the mech runs past the ramps and crashes at the ends. This 1 does that and I made sure they r open. I found they must have tie wrapped the mech for travel in the Detent sw area and it was bent and not functioning. I bent the bracket back and I can see the sw open & closing. If I run Ron's test #1, it does not show the pulse timing . Instead it just shows mech position , like 135, etc. Is the timing of the detent sw critical that would cause this not to work? Any ideas to try? Thx, Kent
