LME49811 and PNP Quasi

[kroto]

I wan't to build this amp :

Q1 : I have no experience with Quasi complementary Pair, furthermore a PNP Quasi.
Is that PNP quasi configuration will work?
I've been simulate(LTspice) that PNP Quasi with discrete amp, and it just work fine. But I need confirmation from a real world experience that this PNP Quasi will work.

Q2 : If that circuit is OK, how much chance it will oscillate?
I don't wan't wasting my money on smoke.
- Should I add a compensation cap across base-collector of driver transistor like Sziklai pair does?
I've been read a thread suggesting to add R 3k3 and 75pF ceramic to compensation pin of LME49811 to maintain stability, so I add them.

Q3 : Is the layout OK? Will it safe from oscillation and hum?

thanks in advance.

Have a look into BuildAudioAmps and Project 19 you`ll find a Quasi with NPN and a lot of other amps using LMExxxx
