"Not linear" is the answer I guess. But we have derailed the thread too far I guess 😀 Let's refrain a bit (or let admin to create a new thread if he thinks it is best)...
In case anyone cares, I'm listening to some Ella Fitzgerald through my DX Super A as I type this and it is absolutely stellar!

Is super A a lot better than plain Dx? As J type - I am listening to Suzanne Vega on my Dx and it is one of the few amps to handle the deep bass line properly on many of the tracks on 9 Objects of Desire album. It's a nice amp - you would be hard pressed to find a better commercial amp for under circa $1000 is my guess. That's the cool thing about DIY. If the FX8 tops this it will be very cool. I am really liking the small form factor because I want To build a 6 channel amp for my 3 way active setup. 3 amps per side bolted to same heat sink. It may be a small heat sink too if I use a small CPU cooler fan.
Nice work. I suggest to conect relays in series and you must decrease 1k2/5W resistor value to get 24V on relays coil.

Correct, that's more efficient. Optimum value for parallel configuration is 650 Ohms btw. Using 600 Ohms gives currently 25.5V with 40-0-40 Transformer in idle.
This is VI limiter not protect. you can add this circuit but you need DC protect... you can use only protect circuit from PSP100 without PSU.
I don't want use VI limiter on hi-fi amps, only for PA.

No, there is no short circuit protect, use this schematic.
