All of a sudden, my 2600 decided to only play number 1 records. If I key in B8, it plays B1; C5, it plays C1, etc, It chooses the correct letter, but defaults to number 1.
I have the service manual, but still can't figure it out. Any recommendations as where to look? Thanks.

My first l@ k would be at "coil #1"-- Dozit be "stuck" in the energized position ? Ron Rich |

Yep. That looks like it. The spring won't return the plunger to the up position. Is it possible to correct this without disassembly?

O.K. It looks like alignment of the rotating plate. I can move it just slightly, and the solenoid pops up.

After playing with this more, I see that the number solenoid, no matter which one it is, stays down after selection. This means that the second selection, no matter which letter it is, will keep the same number. The rotating plate does nothing. It never moves. And it appears that it needs to back up slightly to release the solenoid.  ? |

I dono-- way back in 2016, when you joined Jukebox Addicts, didja READ the "Hi Newbies" post in the FAQ's section-- Have you forgotten that it axed you if you had a Service Manual, and some other stuff--probably time to re-read it --- might just tell you what should happen before you play around and cause a major problem !

This is directed to Ron Rich. However, since he is a "global Moderator", I'm sure it will be deleted post-haste by him.
I will ignore the fact that slang such as "dozit", "dono", "didja", and "axed" show one's inability to master the English language and intellectual level.
In 2016 I rebuilt this 2600, and have not tinkered with it since. All I've done since then is completely and successfully restored over 150 pre-WWII radios since that time. I subscribe to other forums, in which the participants do nothing but aid and instruct.
I was under the mistaken assumption that this forum would be the same. I guess I was wrong.
Please excuse me for asking advice to a problem in which there might be a shortcut that would aid me in my diagnostics. I have been in the electronic equipment repair field for over 50 years, and have given many "tips" to other engineers in order for them to expedite repairs.
"probably time to re-read (the manual) it --- might just tell you what should happen before you play around and cause a major problem ! Ron Rich"
What a heart warming and helpful statement.
It's too bad that probably no one will be allowed to read this.
But if, by chance, it is left up, I still would appreciate an answer to my original question. Just not by Ron Rich.

You may write-- what ever you think / whatever you wish-- Or like "the rules" posted in the User Introductions post,stickies. I am a lazy bastard-- too lazy to write out "did you", and so on -- and not a very good typist either !
I can only re-call the answer to your question IS covered, in the SM-- but I was not only referring the the SM, but the "requests" in the Hi Newbies post. Ron Rich

There's a procedure in the manual I think you need to go through, see page 9. However I'm a bit confused by what you mean when you say the rotating plate does nothing - does it not move at all, even when you release the jammed number solenoid plunger and select another number?

I'm going to try this again. Hopefully without sarcasm and useless "help" such as "read the manual".
NO WHERE in the manual that I can find does it list the series of operations. What is the purpose of the rotating plate, and when does it actuate? This unit was working perfectly until recently, so therefore, logic suggests that is may be only a simple adustment. I do not want to disassemble the unit and check all adjustments in areas that do not contribute to the exact problem I have. I want to go to the specific area that may be causing the problem.

Norman. Thanks, Norman. I have read page 9. The rotating plate does not move at all. No matter what I do. |

So you are saying that you can't even move the rotating plate manually by turning the nylon gear as described on page 9? In which case, something is jamming it; this is most likely one of the number coils stuck down or bent and jammed. To answer your other question, the purpose of the rotating plate is to line up the number that has been chosen. It's hard to say whether you'll need to dismantle the selector assy to fix it - first you need to determine what's causing the problem.
I think there is a Wurlitzer manual that has a decent operating description; this has been discussed before so you should be able to find that by looking through previous threads. I do recall that it's a manual that I don't have so likely 3000/1/2/3 or 4.

I keep reading back through this thread and I'm still not at all clear what is happening! Are you saying that if you make for example, selection A9 that the number 9 solenoid enegises but doesn't release? And that the plate doesn't rotate at all via the motor?
Norman.

That's exactly right. But if I back the plate up by hand slightly, the solenoid releases. The motor never turns. |
