Hy to all of you,
Someone can help me to restore my new “old” Rock-ola microphone kit-2130 and connect it to my Rock-ola 484?
Someone has the manual and the wiring diagram of this kit-2130 please?
On the manual of the 484 says that this kit is compatible
Thanks

After a recheck of all components, unmount the amplifier and reclean all components, remount original cable (clean and checked) the new M44-7, the resistance on both the channels are 0,66 test with my multimeter on scale 20k ohm.
Test the jubox and...
EUREKA!!!!
Now my Rock-ola works great in all parts.
I have restored my jukebox!

In the Rock-ola 484 the 2 ground are joined together so arrive 3 pin i

Now the sound and the volume is better.

In my Rockola 484 there is only one capacitor/filter, but 2:
- 2500uf 35vcd
- 1200uf 50vcd
Can i replace with normal electrolytes capacitor of the same uf and vcd?

Thanks Swen but I haven’t understood what you said on the first line (Schraub das Netzteil ein Feld weiter links auf)
Here i have attached the schemas, can you explain me please?
As you said, i have only to replace the two capacitors C101 e C102, right?
Because I don’t see one of these capacitors break

Ok thenks
For the short circuit that happens randomly, what i must check?
I haven’t seen cut cables or something else...
The only strange thing is that the output cables of the transformer are dirty with a grass gel as shown in photo...
What can i check?

I live in Italy.
I’ just bought 2 MC14503B to replace the old CD4503, but nothing is appened, it’s always the same.
Now i will buy the 4069 as you say.
For 4069 on the board are monted the CD4069CN but now are different...
There is CD4069UBC (the datasheet says Equivalent to MM74C04)
Is it right?
Thanks
