Sequence of operation

[Restorationnut]

Finally! A dedicated forum! I restore radios from the 1930's and 1940's, and have just expanded into jukeboxes. I'm starting with a Wurly 2600. I've already re-capped the amp, and am starting on the mech. I've found somewhat incomplete info in the manuals, because I've been told that the manuals were designed for people that have been to Wurlitzer school.

What would REALLY help me, and others from what I have read, would be a sequence of operation. Knowing which relay is triggered by which switch, etc. would be invaluable, and a lot easier than trying to figure out the sequence from hard-to-understand schematics and wiring diagrams.

I did read that such a document might have been written for an earlier model, but I cannot find anything for the 2600 era units.

Does such an animal exist, or can someone create one?

Thanks, and thanks for the forum!

Welcome Pat.

I don't know the answer to your question I will let someone more experienced answer that.

I just wanted to give you a heads up that you will need to register in order to post in the future. I didn't realize the forum was set to allow guests to Create Threads so thanks for pointing out the security hole its now been corrected.

Pat,
As far as I know, WurliTzer did not put out a sequence of operation manual for any model. As you pointed out, they relied on "factory service schools", as did all coin operated phono makers ( except, possibly, RockOla?). This was due to the fact that a coin op phono was NOT considered a "consumer product". WurliTzer was unique, however in publishing what they called "a functional schematic", for each model. I did attend one WurliTzer school as an invited "guest"--where the instructor did "teach" how to read that schematic--and I was told the every school contained some instructions on this subject.

Thanks Craig and Ron,

And glad I could help, even though it was accidental. I have time, so I think that once I completely understand how the 2600 operates, I can go ahead a compile the sequence for others. Unless, of course, it's already been done and the creator finds this forum.

Hello Pat,

I would also replace the plate and cathode load resistors in your amp. These drift in value as time goes on and this will affect the linearity and gain of the valves. Easy to do, costs a few cents and it will improve the performance of your amp. Many don't bother and do half a job!

Regarding the sequence of operations on the 200 select system, as others have said there are 'updates' that Wurlitzer provide in each service manual. IIRC the 2100 has the same sequence of operations as the 2600 for the mech operation. Have a look-see in one of those manuals.  I have attached an example to see if it is what you are looking for.

Thanks Martin, I usually make a habit to ohm out all resistors when I re-cap. I've got to put the 2600 on the back burner for awhile as I'm getting backlogged on radios. But that will give me a chance to study the 2100 info as you suggested.
