Is the noise the same one you were concerned about that sounded like the audio file I posted?
I don't see anything on a jfet being used in the DC circuit. The control circuit does use a jfet in some amps.
What are the circuit board designations for these two transistors?

Yup same noise Perry after taking the LV supply off and putting all outputs and rectifiers back in the noise is still there it's not real loud but definitely noticeable even at quarter volume you can hear the high pitch noise fading in and out.
PART designations are Q275&Q81 pics below.

They are jfets in some of the newer amps.
If that noise is like the noise I posted, you will probably have to redesign the amp to repair it.

So it's just a noisy amp is that what your saying because I don't have enough knowledge to redesign it lol
I thought it might be my power supplys but I've tried multiple supply with the same results but I could be just being to worrisome
I'll try it in a car maybe that will help the noise die down
