I wonder if I can replace the obsolete 2SK30 with J112 from my stash.
Would you happen to have the PCB layout handy or a copper side picture? Otherwise I will have to do some reverse enginnering...
To stay in the thread, it seems to be biased at 100mA per pair of mosfets.

100-120ma has always seemed like the sweet spot in push pull arrangements.
Also, the Fair-Rite #2643001601 has worked well to help with oscillation when using lower value gate resistors like 100 ohms. Use them on both the gates and drains.
All kinds of other great info in the Exicon data sheet too.

So, have you built the schematics you posted? How does it work?Yes, I think 100 mA is a good level.
Thanks.
I got the pcb layout from JM Plantefève. Will post it in a few days when I am back in town. Got all the parts and will start soon.Bonjour guys. Any progress with the nrds amplfifier ? I am very temped to build one. Is there any pcb layout available ? or is the layout to be made (not a real problem either, with so many pcb professionals on diyaudio.
