Hi,

I've been replacing all the caps

Coupling / decoupling ?

in my vintage Wurlitzer Jukebox amp.
The problem was one channel was buzzing quite badly. Now ive done it
all, the bad channel has stopped working altogether (only a slight
hum). I checked my wiring and noticed one of the caps I changed is
the wrong value (22uF instead of 150uF). This cap is in the faulty
channel. Does anyone know if it would make that much difference?

I think you need to stop messing around and consult a proper tech. I
doubt you have the skills to fault find.
