Agh, noooo!!

Taking apprentices perhaps? I'm also old and slow, but with two of us, we'll be ... twice as slow

Thanks Mr. Pass, Papa - off to the article now!

Just finished a fast read of the article looks very interesting . The change from the IRF to Fairchild devices is this because they sound better, or is something else changed ?

Also I look forward to adding the P3 to my current F5 to see what difference it makes to the sound.

Thanks Nelson for this I look forward to the building process and listening. I will start with the V2 , but the V3 and beyond looks like it will keep me occupied for many months to come.

Just one question Nelson

,

The original F5 i've built has a sound profile (signature ) that gets visitors to my humble abode drooling...

I remember you saying that if you raise the power you also loose the magic...

My question is; does the character of the amplifier change with this much gain in power ?

I know i'm just being impatient...i need to build one.

Cee

Pa explained that in article - up to 3 output pairs , everything is pretty the same

after that ( with more outputs ) just double inputs

doubling inputs will not have any negative effect , especially when using cascodes on them (because of No Herr Mueller)
