I got a response from Luke Creek, very nice of them...
"The HUF76339 device is a suitable replacement for the BUK555" I think thats a typo. its the HUF75639.
in case anyone was wondering. I also found R20/R120 toasted, still waiting on parts. He also sent me the 4330v2 schematic.

Generally, for audio, you don't want low Rds(on) which is characteristic of most newer developments in switching devices, but high Rds as in the BUK555 are better from an audio distortion POV.

HUF75639 will certainly work but make sure it is the right P3 suffix type for a T0220 style package or it will be something else. I suspect it might not be ideal due to low Rds.

IRL540 NPBF looks closer and is available widely, from Newark at least in the US. Note that max. current rating is only ~30% of the BUK555-100.

Hi I think I have a small rail with BUK555 devices. Will check if you still need them.

Amp is back in service, I used IRL540 from mouser. Found zd3 was dead and r20/r120 out of spec. Thanks for the help. If anyone needs the 4330r schematic let me know and I can email it. The bias setting for this one is 3.5mV, thx again.

Tried to PM but it appears you're not accepting PMs at the moment.
