F5 original .47R vs 0.68R ???

[mfrimu]

Hello,

Not sure if I go for R1 version, but I have both 3W resistor pairs:

0.47R and 0.68R

Which should I use????

I searched the long F5 thread, but can't find the answer....

Thanks !

I would fit the correct value.

Either will work fine. The .68 will be a little more thermally stable and has a
little less open-loop gain, and thus a little less feedback, but nothing wrong
with that.
