Rockola 448 Jukebox with amp 47160-A
« on: February 03, 2020, 12:55:59 am »
Hi
I’m needing help on my Rockola 448.  I am unable to get any sound out of my jukebox.  Ran the troubleshooting from the troubleshooting guide with the volume control and the input from the tonearm.  Produced no answers. Voltages are present at the power transistors. Q5 and Q6 are -51 and -25 VDC respectively.  No hums or any clue as to why it’s not working.   Could it be the mute relay or associated switch somewhere?  Thanks.
