Thank you AudioSan. I just ran across a post #365 from Buzz describing the XA160.5 and more Fets with lower bias. No matter how many times I read a thread, I always find something new.

I have my fingers crossed that someone will come through with an F5Tv2 in a 5U chassis from the store as a dual channel amp. I know that at least someone has thought about that setup.. it must be..

The 5u chassis will handle the heat from a V2. Might eve. Get away with v3 at half bias and no diodes. They will sound different.
