Hi Everyone, I'm trying to find a mute relay for a German Wurlitzer. In this case a Baltic 3. Part number is 18010022. Flippers are out of stock - Anyone got one they would like to part with? Thanks Iain

Re: Stereo cart wired mono - what new, impedance resistance?

Fill me in a little. Was the "redhead" a ceramic or magnetic cartridge? And the cartridge you're using now, is it ceramic or magnetic?

Yeah I saw that the redheads amps/preamps expect 47k, so was thinking for the stereo wired in parallel it should be half that. But I guess it’s just whatever sounds good? I did read that it’s important not to go too low (or let it drop to no load) or the cart can be damaged. Not sure if this is true. I’ll probably put it back to the 39K then. I recall it sounded fine - I just changed it because it was suggested that I restore it to what was in the schematic not appreciating that the stereo mod might make that not the best advice. > Thanks, > -steve. > > > > On Feb 14, 2026, at 1:31 PM, js--- via Jukebox-list <jukebox-list(a)lists.netlojix.com> wrote: > > > > It's not a hypercritical value.

Wurlitzer Early CD OMT
by Tony Miklos 16 Feb '26

16 Feb '26

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

It's not a hypercritical value. Normally, you would get an idea of the value from the manufacture's suggestions in the little pamphlet that would accompany the cartridge (or the jukebox). Far more critical are the tone shaping circuits in the amp itself... which compensate for not only cartridge characteristics, but also record characteristics (with RIAA being one of them, after a certain date) and room characteristics (if the amp offers controls for that). > Hi Forum, > My first juke restore was an M100C that had been modified with a G amp and a stereo redhead cart wired in parallel to feed the mono amp input. The amp had not been totally rebuilt but did have a few caps replaced (quite some time before). It also had the cartridge impedance resistor changed to 39K from the original 10K. I’ve since learned that the 10K was the appropriate resistor for the original blackhead carts, so when the conversion was made to the stereo redhead this resistor was changed. My question. Is - why 39K? > > I know that the redhead expects a 47K resistor. I’ve seen multiple posts suggesting that when using a stereo cart wired in parallel that this resistance should be doubled - or perhaps even a bit more. I would have thought that the resistor should be changed to the equivalent of two 47K resistors in parallel (47K/2). Agree? > > Anyone have any insights why 39K? I changed it back to 10K because at the time I just thought it was a mistake and the output level dropped, which makes sense. I am thinking I should change it back but would really like to understand what value I should use. The mods were clearly made by someone who knew what they were doing, so I doubt the 39K was just a mistake.

Stereo cart wired mono - what new impedance resistance?
by Steve Swaine 13 Feb '26

13 Feb '26

Hi Forum, My first juke restore was an M100C that had been modified with a G amp and a stereo redhead cart wired in parallel to feed the mono amp input. The amp had not been totally rebuilt but did have a few caps replaced (quite some time before). It also had the cartridge impedance resistor changed to 39K from the original 10K. I’ve since learned that the 10K was the appropriate resistor for the original blackhead carts, so when the conversion was made to the stereo redhead this resistor was changed. My question. Is - why 39K? I know that the redhead expects a 47K resistor. I’ve seen multiple posts suggesting that when using a stereo cart wired in parallel that this resistance should be doubled - or perhaps even a bit more. I would have thought that the resistor should be changed to the equivalent of two 47K resistors in parallel (47K/2). Agree? Anyone have any insights why 39K? I changed it back to 10K because at the time I just thought it was a mistake and the output level dropped, which makes sense.

1958 Wurlitzer 2200 record jams while clamping record
by Rick Force 12 Feb '26

12 Feb '26

Hi all, the records on the left lifting arm (side one) tend to jam while being clamped and the turntable can't turn, the right side ( side 2) seems ok. I have to reject the record to clear it. This all started after the move, it was fine before that. Doesn't happen all the time. Seems like the left lifting arm isn't going up high enough to center the record with the tt hub when this happens. Thank you all for any help on this, Rick.

Rowe AMI JAL 200
by The Day Family 08 Feb '26

08 Feb '26

I have a JAL 200 from 1963 that registers a selection but picks up and plays a different selection than the one selected the majority of time. Often picks the same selection like it was not reset after playing. It is the first 1100? series mech (tone arm on left side of turntable). Where should I start, I assume something dirty. Thanks, Jim The Day Family jwdlad(a)verizon.net
