[Jukebox-list] Wurly 2410 - the other percent

[Jimmy Day]

Yes, this is the FAMOUS Jukebox Jimmy Day. (grin). Thank you for those kind 
words, Jackie! When you get the amp back, let's set up another meeting and 
get everything going.

For the group - here's what we found...

Jackie was really in the right area when she was asking about the switch. It 
is the motor reverse switch; as soon as the scanning lever contacts a pulled 
pin, it actuates this switch, which actuates the reversing relay, to 
immediately reverse the DC magazine motor and puts the mech into the load 
cycle. Forgive my terminology, up until now, my knowledge of this mechanism 
was zero, but I am impressed with its simplicity. That "Play-Rak" is a great 
idea!

Anyway, there are two switch stacks on the rear of the mech, the one on the 
right was the culprit. I believe it is called the "play-mute" relay - Jackie 
has the manual, and I think that's what it is called - and so, this switch 
is supposed to be in the "left" position during entire cycle, being held 
there by a spring, and only switching over when the tone arm sets down. 
After much head scratching, we came to the conclusion that the spring was 
not strong enough. I had to cut two turns off to get it to where it would do 
its job. Apparently, the mechanism "thought" it was playing a record, since 
this switch was always in the "right" side position. I haven't looked at the 
diagrams or anything, so I really can't say exactly what was happening. 
Anyway, it was a process of cycle and observe, as Kyle pointed out. Switches 
and levers that don't move when you think they should, check them out.

We ohmed the microswitch, it was good. Jackie had already ordered another 
one; we might keep that as a spare. This whole jukebox is clean CLEAN, and 
the mechanism is CLEAN. Looks like a low-mileage machine, and she did a 
super job of detailing it! It has the green Cobra and I told her about 
playing stereo records with it. The amp wasn't working at all, all heaters 
were lit but the 5U4 was not. Turned out the locating pin had broken off the 
5U4 and the tube was one pin off. Then we had sound, but very low volume, 
and wiggling the preamp tubes resulted in a tremendous crackling, and one of 
the 6L6s seemed to be way too hot, so I left the 5U4 out for now. I also 
suspect the -28VDC is low, the selenium rectifier probably needs replaced.

We ran over some of the adjustments, the keyboard contacts are still a bit 
troublesome, and the latch solenoid is not pulling in. If pulled by hand, it 
stays, but I didn't pursue that further as I wanted to see her Seeburg C 
downstairs! There may be a switch for that solenoid that needs adjusting; 
the two ww resistors near it were quite warm.

The cable that actuates the stylus brush had been replaced with a piece of 
string with a paperclip hook tied to it (by the previous owner perhaps), it 
seems to work and we'll let that be.

The top glass reads "Wurlitzer Hi-Fi Stereo", but the jukebox is definitely 
a mono machine, down to the ID plate. An "S" suffix would denote stereo; 
this is a 2410 period. No big deal. There is still a small issue with the 
right lift arm, it tends to bind if there is no record in the slot. I'm sure 
we can fix that. And one of the duckbills broke off, the 100-select uses the 
stationary ones and according to Dr. Wes Dean's book, if we can find a 
Prince Albert can, we can make one.

All in all a fun rainy day! Jackie and I will keep y'all updated. We made 
two little videos we made of our project, just for fun. I'll post the links 
soon as I get them uploaded.
