Fast Autoranging DMM
by Tony Miklos 31 Dec '25

31 Dec '25

Does anyone know/use a really fast autoranging meter? I'm looking at this one to try. (I didn't see a price yet) I think it takes .8 seconds to read but I got that spec somewhere else. https://www.eevblog.com/forum/testgear/fastest-dmm-ohm-autoranging-suggesti… I'm so used to my ancient Beckman 310 being so quick, but it isn't auto-ranging, so that of course makes it slow if I have to turn the dial. -- Tony Miklos Tony's Jukebox Repair

Wurlitzer Early CD OMT
by Tony Miklos 31 Dec '25

31 Dec '25

Someone got to this before me. I have no idea what may have been wrong or what has been done, except this. The CD player acts like it's typical failure symptoms, but it tests good and a different known good one doesn't work. All the flaky BC337's (it's in the serial number range), they were all replaced with 2N2222's. But transistor Q15 was also replaced with a 2N2222 which is a BC327 NPN not a PNP BC337 Could that one transistor cause the cd player to not work? I'll install a replacement, but the juke is over an hour away, so I'd like some idea if that one transistor could have been the problem or if I'll have to dig deeper. -- Tony Miklos Tony's Jukebox Repair

W1015 sound system Volume box
by M De Simone 31 Dec '25

31 Dec '25

Seasons Greetings! I’m working on a Wurlitzer model 503 amplifier and volume control box (all original). This set up also has a Jacobs preamp installed. I’m having issues with the volume control box (I believe), I’m using an iPod for a signal, when I plug it directly into the amplifier it sounds great, when I use it to test the preamp there is a slight increase in signal from the input to the output, so I’m assuming these components are all good. When I connect the volume box into the circuit I lose almost all the signal, everything is newly replaced in the control box except for the coils. I’m suspecting L2 but have never had to replace one and not sure how to test it? From the schematic I’m guessing one of the tabs on the coil is just an isolated binding terminal, I suppose what I’m asking is how to test and find the issue and if need be where would I source a modern replacement? Thanks for any help, Mauro Sent from my iPhone

Seeburg Turntable bushings 100R
by Jukebox Repairman 29 Dec '25

29 Dec '25

In 25 years of repair I’ve never had the need to change a set of turntable bushings which obviously requires turn table removal. If any members here have performed this mech surgery before are there any tips you’d care to share to make my job a bit easier? I’m guessing that after 70 plus years the turntable has probably bonded itself to the bearing(s) Appreciate any tips. Regards Rick Jukebox Repairman

Continuous scan Seeburg DS 100
by dvachon3＠teksavvy.com 28 Dec '25

28 Dec '25

Happy Holidays to all. I have a DS 100 that continuously scans. It will pick up selected records but won't stop scanning after the last record plays. The subtract solenoid does not move when the mech scans to the right. I checked the subtract switch on the back of the mechanism it has continuity even with the blades separated. The subtract solenoid in the selection receiver doesn't seem to be stuck. Is there something else that I should be looking at? Thank you, Doug

Rowe/AMI Trunnion Pin
by Tony Miklos 20 Dec '25

20 Dec '25

Hi John if you are reading this. Not too too long ago you posted about a trunnion pin wearing a hole in I believe a shaft. I was looking at an R-91 manual and happened to see a trunnion pin listed and it's relative location, but the diagram doesn't show it. Is it shown in older manuals? Thanks, Tony -- Tony Miklos Tony's Jukebox Repair

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
