bara dual front end

[kt315]

planning to do a dual front end for bara... some kinda of universal converter board, at DIP-8 socket, for a P-channel MOSFET PI...
any thoughts? offer IC, max412 is poor as low slew rate 4,5V/us, unfit.

Why not with an N-Mosfet?

traditionally. we change PNP type transistor on P-channel mosfet. both, bara and surf, have PNP transistor in original ussue coil drive.
