Without the jumper, when you reintroduce rail voltage. The jumper is required because the amp loses the ability to correct for errors in feedback when you take rail voltage from it. It's not always necessary but can force the duty cycle close to 50% if it doesn't go close enough without rail voltage.
Perry the difference of the voltages with the rectifiers is minimal I have the same input signals in the LM5110 when I had the jump without the rectifiers the yellow LED is flashing the difference of the signals is at the output of the LM5110 circuits and in the gate of Some MOSFET I attached the images the first is the output of 5110 and the second is that of the gate of Q2014 and Q2011

Sorry for the translation error, the amplifier has never sounded, it only produces the audio of the flickering output. I have checked the signal from the rca input and the signal does not even reach the controller card I found a tl072 with false welding and even so I do not observe any signal I also have no ground in the input rca. This amplifier is a headache
It sounds like you have two problems. The amp should oscillate with or without signal from the RCAs. The no signal problem could be from a dirty switch or pot.
Do you have any low voltage power supplies with an isolated output?
A small 12v battery or maybe even a 9v battery would work (they work on the older BD amps)? 2-3 18650 type batteries in series would work.
