This design is very good for HI-FI, but there was some limitation for PA use.

Adding output transistors, and using higer power voltage will not give higer output power, that is limitation for PA use.

Yes I use this amplifier in bridge, but only with 8R load. For 4R load use PSU with +/-50V in bridge mode.

When I say "PA", I say "Professional Amplification" or "Professional Audio" and not "Home Amplification" or "Domestic Audio" We talked well in Serbia
