You could try MTX but I think that they've gone to the dark side.
I can't understand why manufacturers don't distribute diagrams. There isn't one competent engineer working for an amp designer that couldn't reverse engineer any design out there that doesn't use PICs. For the most part, there is nothing that can't be easily copied. The only people that withholding literature hurts is the service industry.

Yeah I tried MTX and they won’t give any information out .
I might be able to figure out what caps go there .
Is there any way to tell what transistor goes there if it’s an npn or pnp by the voltages ?

For the caps, start with at least 10uF and voltage above what you measure across the pads. Recheck the voltage after the cap is installed.
You can probably get a good idea of what needs to be in each location by the voltage on each leg. There was another missing one across the board.

I don’t get this amp I replaced the parts but as soon as I hook it to power it burns the whole regular circuit .
So either I’m gonna have to put it back together un repaired or find someone with pics of the amp so I know what transistors where .

This amp may not be worth the trouble but installing larger parts via wires with an inline limiter may allow you to troubleshoot.
I'm assuming that you meant regulator circuit.

It's burning the 15V circuit? Are there any shorted devices? Does it use 78xx regulators or transistors?
Back to this amp .
I have a question hopefully someone could answer .
There is 1 transistor missing and could be one of the following MPSA42,56,06
The emitter of the transistor connects to the base of an mpsa42
The base connects to the emitter of an mpsa56
And the emitter connects to the outer legs of the rectifiers .
Does anyone have an idea of what transistor this might be out of the ones listed ?

The outside legs can't be directly connected so the emitter of the transistor can's be connected to the outer legs (plural) of the rectifier.
The 3rd leg of the transistor in question connects to the stripped side of a diode then to legs 1-3 of the rectifier
Sorry it would be the collector that connects to the outer legs of the rectifier .
So wondering which transistor I should use

I figured out the transistors .
For the power supply fets would the 3205’s work or what do you recommend?

If the 3205s are equal to or better than the originals, they should be fine. That's what I would have used.
