Does it still beat vanila F5 though? I guess it should because of the better symmetry between the push pull fets?
if you're going to differentiate them by your ears/brain combo , there is no other way than to try them both
for me - F6 , even with IRF outputs , will beat F5
for me - F6 , even with IRF outputs , will beat F5
How much of the better THD with the SS Jfets is due to less degeneration (near zero) and higher transconductance resulting in more overall global feedback?
Look at the F2J, degeneration, no feedback...... One third of the distortion of the F2 with IRF.
So I think most of the better distortion values is really due to the SS.

Will the PLH amp work also better on R100 transistors then ?
(I've got PCB done for PLH but no will to do it).

except few residents , it seems somewhat silent here ......
I'm thinkin' of F6 lookalike with 2SK60 and 2SJ18 ( so having complementary pair of VFets) , using 600:1200s ( meaning 150+150:300+300) repeater .
logically ,connected as 150:300+300 , having some 3db in xformer phase splitter itself
but , that's on loooong rope , having at least 3 projects tied on same line

Got some hetefor that very purpose, but my rope is even longer. So you think you need voltage gain cause of low gain. I want to try laterals too. I like them a lot.
frankly - I don't need more amps - (almost) everything is good enough , while music matters most
but , parts are what's urging me to make amps

Just enjoying the F6 😀😀😀
When Tea Bags boards are available will try to compare the Jensens to the Onetics that are currently installed
Maybe somebody will release other SITs in the next year or two 🙄

I have been playing with F6 Degeneration and distortion (which goes higher when trying to maximize 2nd harmonic in my guess) and then trying to evaluate the sound to my ears. It certainly changes the sound. Darker I think.
Trying to rest more, lots of virus activity here in US and New England.
I really don't want that, after already recovering from something.
The VFET idea sounds great. I would try that if Acroman's parts would work. I've been evaluating Mike R's amp too.
On the list is matching some SemiSouthFan's parts.
Some people have been really helpful in all this - They should be mentioned.
Generg, Flochini and Buzzforb. Keeping me on middle path.
Tea-Bag needs counselors to keep his progress going when ideas become stronger than action.

Ideas are dangerous an dplentiful. When seeing my curren tproject, wife simply asked," what is this". Poor thing.
The onetics was sharp to my ears, but when adjusted for second seemed to blend really well into nice mixture. Try it out.

I spend (waste) 2 hours a day reading all the threads I am interested in, should be building something. I do listen to my lovely system while reading, so all s not lost.

Would not have got off the ground w/o your help and that of buzzforb,generg, ZM, lhquam, and of course the man, NP
Will be following you with distortion work when my probes arrive 🙂

I hope that you all will have a safe, prosperous and healthy 2013. Zen Mod. Please show a proposed schematic with focus on biasing.what's up , Dodos ?
