The problem is, that your SH-AC300 needs an amp with 5.1 input (but no decoder). For this purpose technics delivered SA-AX710.
So if you'd like to use your current equipment it would be impossible.
The only option is for you to buy 2 more Power Amps (SE-A900S), so that each of 3 amps would take care for one part of music. (one for FL, FR; one for RL, RR; and one for sub and center).
Another option is for you to buy SA-AX710. Then all the problems would be solved with it.

SOURCE: I have a Technics SA-GX470.
I have not solved it yet. I did find a similar schematic of another model. I have gone over the entire board checking connections first. What I see is the minus 14 volt regular running very hot. The voltage is OK but there is something drawing a lot of current. The plus side is cool. I am in the process of looking at all the loads on it but believe it may be the main power module. This unit has two modules with the main one for the left and right speakers and another that is for the center and surround speakers. It is cool and guess the the main one may be bad. Panasonic is the only source for this one and that is doubtful. The prices I have found is around $60 and a little expensive to buy and just try. I am going to make sure it is the problem before I recommend they spend that much up front. Technics is a low end Panasonic product and I have found this to be a very troublesome unit as well as others. It's design is complicated as all Panasonic products are. I worked on this unit several years ago and the same problem went away. I suspect one of the output transistors in the module has gone rendering the whole thing bad. Whatever happened to a simple transistor replacement. I will keep you informed.

Loose connection on "POWER-SUPPLY" and sometimes solder loose on "C I S BOARD" due to extreme - heat of amplifier. $137.51 repair done in 1HR as I waited at CENTURY SOUND ELECTRONICS.
