I would suggest making one of the amp without any of the switching apparatus. Listen to it for a bit of time.
Then switch the amplifier circuit out for the other one, listen.
You are going to have a strong preference for one or the other -- they are on opposite sides of the Pass sound... and you will likely only want to listen to the one you like.
That will save you all the switching circuitry.

Hi 6L6 🙂
I forgot to write that, i suppose! -I allready tried both amps, but i like both, on different ways...
The AlephJ is for me, the most smooth sounding amp, where the F5 is the most "clean"...
Actually, last year i spent hours with my son of 17; listning to both amps, swapping the pcb's in and out two times!
He hear things i don't and listning with him, was a real pleassure 😎

Switching tens of amperes DC (PSU) is not easy, suggest you use solid state MOSFET relays instead of mechanical ones. Much less risk of fusing a contact. Unless you are totally confident that you will never encounter a situation where the two amps cannot be powered up at the same time, and you will never open the contact while the amp is running.
The speaker side is a bit different, but I would still not suggest sharing ground commons either there or on the RCA/power side. It doubles (or more than) your chances of a ground loop.
Makes the switching a bit more complicated, I know, but reed relays on input side can be easily doubled, and you simply need to use DPDT (or two relays) on the output instead of one.

Thanks for suggesting, but i am in a situation, where i can get some not very used Siemens relays, with coil 17-30VDC... Actually i think i can find some, rated right for switching 15-20A DC.
Regarding the safety situation, for not powering both amps same time, i am (I think) capable of making such circuit 😎..
I really appreciate all theese suggestions
