Default Lf351 replacement for Curcio Daniel I

Hello -

I'm buildng a Curcio Daniel I and would like to know what people suggest as a replacement for the discontinued lf351? Something in the Analog Devices or Burr Brown line.

I know the AD 797 will oscillate without a .1uf cap to stabilize it.
Not really my first choice but would like something wide bandwidth.

Anyone have any suggestions?

AD825, OPA627 work well in Jung type regulators. Interestingly, i didn't like these regulators when i built Daniel (1986?) and ended up powering it from a non-regulated tube rectified supply. With today's opamps it may sound different.

I have used OP176 without problems. A significant improvement over LF351.
