Default can anyone explain this amplifier? Audio Telex 2sa500B

Hi
Just got a hand on a pair of these. dirt cheap.
Its for PA application but given the prodigous amount of heat sink, transistors TIPC (20 each amplifier) and a output coupling amplifier makes me wonder can it be modified to hifi or SQ use.

If we look at schematic it has two wings of single ended TIP35C coupled with an output transformer probably step up . so for hifi can we modify like swaping primary to secondary and increasing bias to sort of run it in class A????

It would be very intersting if any suggestion can be provided to make it a diy hifi.
