Default Krell FET substitution in preamplifier PAM 5

Hi All,
I 'Treated' myself to a non working Pam 5 c/o Ebay with one o/p not working.
Can anyone advise me on the replacement of these fets,I'm driving myself mad trying to decide what to use as they are no longer available.I guess I should replace the other channel as well.I've searched for a schematic without luck.
The ouput driver stage contains two pots,I guess the first is input trimming? and the other output Iq.I think it looks a bit like a power amp cct?

They are VP0206N5 and VN0206N5

Cheers in advance
