Limeter is very important on high powered amp to prevent from clipping

Is there a replacement / substitute of LM 411?
I found it hard to get..

Dear Irvinejay,
Finally you are really finished your great prototype, and now proceed the second one. So... Congratulation.......
One important things to consider for us in Indonesia is the availability of the original components, especially semiconductors (transistors and IC). Even they are available, the price are not reasonable for the DIYers.
For the Vertex purpose, I would like to ask you the possibility of purchasing the components in Philipine, could you tell us the better way to buy DIRECTRLY from your country or buying from the on-line market.
Your answer will be a valuable info for us.....
Thanking you and best regards,
Endih
P.S. One thing forgotten, could you share the connection diagram of the overall PCB blocks (limiter, main output stage and PSU)..? thanks...
