Just speaking of safest way. I took the fire it up route. Smoke is part of the fun.

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.

AudioSan · 7th January 2013, 11:37 AM

i did fire up my front-end today. just to make sure the cascode section is working. and it does.
with 25V rails i got 7.4V on J-fets drain relative to Gnd. R25/26 is 10K R27/28 is 4.75K

Brock numbers give you good preset range. First official V3. I hope you like it

Hey,

You guys are distracting buzz, who was on a mission to let us know how a 4 pr 5T would work ....

buzzforb · 7th January 2013, 04:05 PM

And I am so thankful.

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..

buzzforb · 7th January 2013, 04:23 PM

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.
