I have a Wurlitzer 3200 jukebox, I hear sound but not coming out of speakers. Help!

It suddenly stopped working. Does anyone know why it would just stop working? is it the amp fuse? it is the wires connected to the arm/needle? I checked over and over and cant seem to find the issue.

Any suggestion would help. Thank you!

I believe that is a solid-state device. No help here. There are groups dedicated to juke-boxes - I am sure you will get more help there.

Here is forum to try. Never used it myself but might help.

from a year ago... still when you have a major loss of function, check
the power supply first. Multi-winding transformers may allow some but
not all things to work. So lighrs and tube filaments may come on (as an
example with tube gear) bur no sound.

For a tube system you could do a simple test by removing the output
tubes (put them back exactly where they were) and check for DC voltage
on each pin at the socket in the 400V range (to the chassis) with the
power on. If present, might be pre-amp [unlikely] or phase splitter
tube (even more unlikely) but usually you'll see very small or even
negative voltages (less than 100V) if the power supply is blown.

Once you have the faulty function, you can then go for the actual cause.
Presence of good power means the amplifier has one or more bad
components. Blown output transformer usually has one side still working
in push-pull circuits, but if both sides are gone and there are no
screen taps, you will see voltage but get no sound (or really distorted
sound if one or more screem taps still conduct).

Solid state gear is possibly more difficult, depending on the design.
But you can check for volts on the collectors of output transistors,
which typically have collector volts on the can. Do not short it to the
chassis or heat sink if there is a can or chassis mount.

Anyway good luck. Identify the faulty subsystem first (power supply,
preamp, power amp) and then isolate it to narrow down to faulty components.

Simple volt meter should get you that far, then you can scope it or
trace the signal some other way.
