Wurlitzer 850 Peacock light bulb wattage
by Tony Miklos 13 Apr '25

13 Apr '25

Watt watt (pun intended) bulbs are supposed to be behind the rotating polarized lenses for the peacock? I haven't worked on very many 850's, but wow this has a LOT of bulbs! Most of the bulbs were burnt out when it arrived here so I ordered some 15 watt equivalent LED bulbs to replace them. Without looking I forget exactly, but I think it took a couple 25 watt bulbs... or they might be the ones I'm asking about. I surely don't want to overheat those lenses. I now recall that it takes 4 25 watt T7 size base bulbs, I found those in LED also. I didn't get them at Walmart, but someone told me that they carry them. They are used in microwave ovens and other appliances. Also, does anyone know of a QUIET motor for the lenses? The ones from that unnamed parts place are so loud that I can here it over the juke playing at a medium low volume. Unless anyone knows of a better way, if the customer wants to pay, I'm thinking of making a new motor bracket that hangs on two of the speaker isolation mounts. It doesn't look too difficult, even with my limited fabrication skills. And one more thing about the motor, it is 12.5 rpm, is that correct? It seems too fast. Ah... One more thing, does it matter which way the lenses go, like which way faces forward? I didn't try messing with them but the color effects don't seem to be as vibrant as I remember on others. The lenses in it are warped a bit if that could be the problem. -- Tony Miklos Tony's Jukebox Repair

CD player is VAU 1252/00 Can I replace it with a CDM12 industrial Or does it require a PRO1 or PRO2 swap? Regards, Rick

Fwd: Bias adjustment W551 amp
by Shankar Singh 09 Apr '25

Has anyone done the modification below? Was any tweaking of the 6.8 Ω resistor required? What are some of the tested transistor replacements for these Wurlitzer part numbers? 130537-5 130537-4 131262 131777 Would like to try on a 550 amp.

As others have said, not adjustable. Check the values of the emitter resistors at 0.5 ohm (they're probably OK and difficult to check with most ohmmeters), also the voltage divider resistors on the base circuit. Whenever I repair or rebuild amplifiers of this vintage with blown or previously replaced and mismatched germanium output transistors I will typically replace with silicon and change the values of the bias resistors to match. Looking through my notes I haven't done this swap on a Wurlitzer 551 so can't give you the specifics with 100% certainty but if you go that route, use MJ15016 transistors and replace the 2.7 ohm 2-watt resistors with 6.8 ohm in the base circuit. This should do the trick. Silicon transistors are more reliable and far less expensive than the generic NTE germanium parts available today. -- Jay Hennigan - jay(a)west.net Network Engineering - CCIE #7880 503 897-8550 - WB6RDV _______________________________________________ Jukebox-list mailing list Jukebox-list(a)lists.netlojix.com http://lists.netlojix.com/mailman/listinfo/jukebox-list Searchable Archives: http://jukebox.markmail.org/

Wurlitzer key?
by Tony Miklos 07 Apr '25

07 Apr '25

Is there a TF-50 I have one that almost opens a Wurlitzer 850 and the number isn't stamped on, it's scratched on (looks like I did it) (I now have a punch set). I suppose I need an LF-50, but what is a TF-50? -- Tony Miklos Tony's Jukebox Repair
