[Jukebox-list] Help identify a Wurlitzer wallbox

[Chris Ralph]

Thanks Jim, appreciate your paper trail.

I already have a stepper, which is a model 261B. This is one of two models 
they show in the service manual as being compatible, so stepper to jukebox 
compatibility is ok. You said this stepper was definately compatibile with 
the 5220 wallbox also ?

I did not know the stepper was meant to supply power to the wallbox, I 
thought its only job was to handle the selections.

One more question - the stepper has four large plugs which I presume connect 
the chassis sockets labelled "stepper", but I'm not sure where the smaller 
plug with like 5 pins on it goes. It looks like it has a longer cord than 
the rest. What is this plug for?

Chris

Hi:
You are asking some good tech. questions that I don't have all the immediate 
answers for, but I'll be glad to research it for you and get back to you. 
Here are a few basic factoids---If anyone else can assist here,please chime 
in. To get you accurate answers, I'll need to pull it up out if a paper 
library file. You happened to pose your question on a day when I had all the 
2900 info. pulled out for a service job earlier today.
The 5220 family of wallboxes was brought out in 1965 along with Wurl. 2900 
series of jukes that year.    For the 2600 series of 1962, the model 5250 
wallbox was the 200-select model that was offered that year.
It was necessary to purchase an optional stepper switch unit in order to 
interface a wallbox with the jukebox.  This is needed for either the 2600 or 
the 2900.  The stepper unit has an onboard power supply capable of supplying 
enough amperage to power up to 4 wallboxes. If you are connecting only one 
wallbox,this is all you'll need. 
For bigger commercial installations, additional power supply units are 
needed, 1 for every four addt'l wallboxes.     The 261B is the correct 
stepper to use with the 5220 wallbox and a 200-play 2900 or newer jukebox.
Both the older 5250 and 5220 wallbox families used the letter-number 
selection system. At the moment, I'm not sure whether the switching sequence 
was the same or if it differed on these models.  If the sequence is the same 
there's a good possibility that the newer wallbox will communicate correctly 
with your 2600.
Wurlitzer wallbox/stepper/jukebox compatibility are usually shown in 
operational schematics in the service manuals as footnotes or on separate 
service bulletins that were mailed out to Wurlitzer distributors and 
servicers back in the day.   Most of this bulletin info hasn't been 
republished by the companies that print the replicated serv. manuals, so 
it's something of a paper chase to find it all. I'm not complaining, just 
explaining.  I'll probably have a good answer to your question in a day or 
so.
Hope this helps.
Jim Alexander
