Seeburg 45TASU2-H5 malfunction

[mecatronix]

Hello, i have a EPFEAI UQ76H5.
I worked fine at 45rpm for 30minutes.
After that it slowed down untill motor almost stopped.
I searched the www and found out most of the speed troubles come from the capacitors in the autospeed unit 45TASU2-H5.
So i swapped the 4mfd 370vac oil filled cap and 3 other capacitors.
The only 2 capacitors that i did not swap where the 2 x 1mfd 200v Mylar caps.

I make a selection, juke takes record but motor does not run....

Checked and cleaned all contacts at the K relay.
I have 220volt at the K relay contacts but when the relay is attracted trough the selection it does not get converted to 120v for the motor.

I assume i should get 120v at the red testpoint.
The schematics do not show any voltage for the red testpoint.

I swapped the 4x 1N4383 for new ones 1N4007
NO SUCCES..... I swapped the 2 GC-433 Transistors for 2 new ASZ18 transistors, no succes.....

I would like to measure the transformers but....schematics do not show any voltages.

Where am i going wrong??
It all worked fine (each time for 30minutes) before I swapped the capacitors.....

When I make a selection, it picks the record but motor does not run, when i force the K relay back in the autospeed unit it plays the record at 33rpm since the motor gets it 120v from the SCC3-H5.

I find it confusing also that this EPFEAI has the Discotheque art panel but then again it is called a Electra when i look over the www info...

Any tips or help is appreciated, thanks.

Please read ( or re-read) the Hi Newbies, and the Errors Known, posts, in our FAQ's section.
The "test point" is not for voltage testing-- please read your factory Service Manual.
Which Code Autospeed do you have-?-normally the problem you had is caused by a failure of the oil filled 4 uf cap.
I HOPE you do not have 240 volts anywhere near that Autospeed ! Which model SCC and code letter is in your phono ? Which "pricing unit" ? Ron Rich

Hello Ron, the autospeed unit is the 45TASU2-H5. 50Herz.
It is a 220 V version with Red Transformers instead of the 110V black transformers.

It is normal to have 220V.

I explained i changed the caps, also that big 4Mfd 370V.
The control center is SCC3-H5 with red transformers. The pricing unit is a UDPU 4-76 with Code C266.
After that, the motor only runs while scanning and not when a record is in play.

Thanks for your help.
Kind regards, Didier.

Sorry Didier, I have never seen a schematic of an H-5 Autospeed unit ? Just seems ill-logical that it would have 240 vac, when the motor runs on 117 vac ? Ron Rich

[Ron Rich]

Didier,
Try the following, and let me know what happens-- prop the clamp arm back so the speed change switch is on 33 rpm-- allow it to run for 15 + minutes-- move prop out of the way--does the motor now turn ? Post the schematic, or send it to me along with the SCC schematic--what CODE is that SCC ?? ( [e-mail]) Ron Rich

Thanks Ron for your help.

As you know,over here it is 220v 50Hz
Usual the USA jukeboxes are 110v.
Most of the Jukeboxes working in Europe have a Stepdown Transformer from 220v to 110v.
All of those jukeboxes are recognisable trough the black colored transformers on the SCC,ASU,TSA.

Now for some reason Seeburg has made European version jukeboxes.
They came with a powerline directly at 220V.
All of the European jukes are recognisable trough the RED colored transformers at 220v.
All the units: SCC,TSA are powered at 220v.
The ASU also has a RED Transformer that in regular 33rpm gets 220v power from the SCC3.

Actually instead of using 1 Stepdown transformer from powerline 220v to 110v at the jukebox, Seeburg gave all 3 units a RED stepdown transformer from 220v to 110v.

Another confusing thing is this:
My jukebox has a modelnr at the back: EPFEAI U Q76H5
This should refer to the ELECTRA jukebox manual and schematics.....BUT in the Electra there should be a SCC4-H5

Further search made me find out that, i needed the manual and schematics from a Fleetwood jukebox that uses a SCC3-H5.

I hope my explanation here does not make things more confusing ....

I will try your advise from above for further testing.

Kind regards, Didier

Hello Ron, did what you asked for.
Left the motor running at 33rpm for 15 minutes, took the prop out, i could hear the relais in the 45TASU2-H5 because the clampswitch closed that circuit, the motor stopped.

Thanks, Didier.

Hi Didier,
OK-- That indicates an Autospeed failure-- Start by returning old parts, one at a time- One or more of the new ones is bad--I would suspect one of the caps ! The "Red painted" transformer does NOT indicate 220 volt units ! Red indicates 50 cycle (Hertz) units, of either 117, or 240 volts. Voltage is indicated by a "L", (low--117) or an "H" (high-240) Yes-- The model ID tag indicates that you have an "Electra" (PFEA1U aka PFEAU-1)--which uses the SCC-3, not a SCC-4. The "E" prefix indicates an "Export" model-- the stamping on the plate indicates the country and that country's distributor that it was originally shipped to. Ron Rich

Ok, Thanks a lot Ron.
I always TAKE CARE for the difference in RED OR BLACK TRANSFORMERS over here cause we can not mix them in our jukes here.
Red transformers usually have 235V printed on them.

I will try to desolder one at a time.
Nothing smoked or smelled or popped but....yes there can always be a faulty new part.

Kind regards,
Didier.

Didier,
I assume you are using re-printed manuals ? If so, the re-printer has made several errors-- the PFEA1U requires the SCC-3, not SCC-4.

[mecatronix]

I downloaded them from the www.
I do believe you....trough the years several people made money in copying and printing manuals.
Nobody thinks about that they would be full with errors or missprints UNTILL they get pointed in that direction trough people with years off knowledge like you do.....

Thanks for the tips Ron.
Kind regards, Didier.

Once again--PLEASE, READ, the "Hi Newbies" post in FAQ's section-- It would have saved time/frustration, over this subject !
