Try to add increase R15, R16 to 220-330 ohms. I have never seen an amp with lateral fets having 22 ohm only. You problem can be found if you read this... I'll trace it down for you.
2SK1530/2SJ201 are'nt laterals.
22 ohms is given for these devices in AN-1850 (LME49830 app note)

Peranders,
I just downloaded the extract from Hitachi notes.
Why do I have to agree not to post extracts from a 1989 Hitachi document?
That seems to me to be both unnecessary and unreasonable.
Did Hitachi restrict you to such a condition in return for showing the pdf on your site?
Now that i have downloaded the Hitchi pdf, I cannot download another article I would like to read. It says I have reached a download limit !

foldback current limiter
i want to design a foldback current limiter circuit.. imax should be atleast 5 ampere while isc is upto 2 or 3 ampere.. any help regarding this ... any circuit for this ....
thanks in advance...
great! that was a huge oscillation
