How to stop waterboarding

Account my sound room which is all on one line(no other way to hook it up) I have waterboarding issues through my speakers.(constant low bass pulses). Is there a power conditioner that would achieve continuous 117 volt output- I would hook my preamp only to this. I’m hoping this would stop the waterboarding issue.

I suspect OP means "motorboating" which admittedly is a form of torture to the ears.

 I think your correct, "motor boating" is the term, a form of low frequency oscillation, it can be had with tube amps. It can also be a condition of air born LF feedback back to a vinyl turntable.

Which out of these do you have powder1 Tube or vinyl?????????

So"....... I changed the rectifier tube 5r4gb instead of 5u4 on the..line stage The 5r4 draws less voltage to work properly and the “thumping stopped immediately.
