[Jukebox-list] Speaker ground

[Bill Taylor]

Hey Guys,

Hey, with my wurlitzer 1900, when the speaker plug is
plugged to the amp, the secondary winding of the
transformer T1 for high voltage uses ground thru the
plug for the center tap of the winding.

Ok, obviously they don't want you to start the high
voltage without the speakers connected to the output
amp. Ok, I understand that now, but... why?  What is
the problem without the speakers connected?  When I
work on my amp I use it on my bench.  I thought I
could just jump the ground to start the voltage
without the speakers.  What happens without using the
speakers?

And, if that is something I shouldn't do, then my juke
has plenty of speakers.  On the bench, I can't put all
the speakers on the bench?  What can I do instead to
work on the amp?  Will just one small 8 ohm work?

Teach me guys!

Thanks!

Bill Taylor
