That seems like a reasonable table of values to minimise the resistance variation due to temperature induced effects when very high transient signals pass through.
A normal F5 runs on +-25Vdc supply rails so the table could be completed by adding in a 20Vpk output and using a 600mW resistor. We are back to the original now.
Andrew,
I wonder if you'd consider adding a couple of columns for me.
+- rail voltage and maximum output power.
I think alot of builders would find it very useful (I certainly would).

and when in the feed back loop ~10%For best sonics, imo, oversize ALL resistors.
My rule of thumb is to run them at <50% rating.

I also like fat traces and big pads... space on the board (if possible)...

Same here. It doesn't cost any more to leave more coopper on the board so why not? The extra space costs but I don't care.
me? reasonable?
Ha!

Duly noted
I also like fat traces and big pads but I also like compact boards.
I don't see the need to have a crowded board if it isn't neccessary.

Especialy when things get hot

Fair enough.
They're not crowded at the moment anyway.
Alternative would be to gang-shabang for 10R in TO-126.
Means switching positons of R5/R6 and the testpoints, to make room for a heatsink.
(Caddock MP915 for under $2 or Bourns PWR221T at $1.35, for 100 up)
Jacco,
What are the pin spacings for those?
