Hi, I have purchased this stage I fix broken and I would like to move my rockford HX2 power 12 ".
Well, at first glance, Q104 and Q110 burned noticed (I remember)
Replaced: Q104, Q8, Q110, Q111, Q112, Q25 and U14
Turning on the stage, the power LED lights and LED protection, do not produce any sound through the speaker output.
140V are present in red and black wires.
Two minutes is very hot, Q15 and Q16 (LM 317 and LM337)
Should I also change these two? Where else should I look? Please help

Hey, Perry, today I received the TL072C, and I've installed.
Now what happens is this:
When connected, it turns on one second LED protection, and then turns off.
The speaker produces a pink noise low (ssssssssshh)
Q16 and Q15 are heating up as before (in five minutes, they can not be touched)
What do you think?

Tone generator, no .... but I have the cd IASCA 2003, where they come from many different frequency tones ...
Do you think we can do?
wait ...
I reconnected the stage ..
This time I put the volume to near maximum mp4, and turning the input level of the stage, produces sound ... but .. nearly full too!
I have also observed that without any input and turning the stage level to the maximum and minimum consecutively, the speaker cone moves up and down at the same time ..!
The pieces were heated above, followed by heating.
Pink noise is still present.
Between red and black wires is 94.2 v.
Why in the positive supply is 43.3 V and 46.3 V negative? (always with respect to ground)
Should not be the same voltage?
Well it's late and I'm going to bed.
I await your reply, greetings.
