I meant NTC instead absorbing resistors. They are shorted second later, and don't care about the load.

Your circuit looks really good, but I decided to play with pics earlier anyway

Does it make much difference to bypass NTC with a relay? Do you lose much with the NTC by itself?

I built a 350WRMS amp 2 years ago, with a large NTC, but have never bypassed it.

Would the rails sag less with a relay, or is the difference insignificant???

Probably insignificant. When you think about it, if the NTCs were to cause any significant drop, they would heat up like mad with any high amount of power!

Sweet!

I do notice the NTC only gets hot for a few seconds from a cold start when the power caps are discharged. Once the caps are charged, you can turn it on and off as much as you want, and it never gets hot.
