Hey Paul,
Do you see any problem using a switch to select between the C4s and the original 150k Ohm plate load resistors while the amp is running?
Can that hurt the transistors on the C4s?
Thanks in advance,
Lee

I would put the switch inside the amp so you have to power it down and flip it over to throw the switch.

So no hot swapping, I kinda wanted an instant A/B switch.

I can see the problem with arcing on the switch contacts.
