F6 Amplifier

[flg]

What sound has Nelson achieved with his F6. Only he and his buying customers know and experience. Flip side question: What will your Teaser6, buzzforb's Franken6 , triode_al's, flg's other DIYers' sound in Mr. Pass's experimental setup? You'd love to know! Maybe for a modest fee, Passlabs [or an entrepreuneur DIYer amongst us] test the subjective and objective performance of your Teaser6 compared to an authentic [investment] F6, and issue a Certificate? For all I know, you are well-equipped to do the testing of amps by other DIYers! It shows through your posts.

No, for now I just wanna try somthing like this:

A little like the WimDeHaan schemo I posted a few pages back...
We'll see how well it works and go from there...

 

[buzzforb]

I assume the Lundahls you have dont mind the DC? Looks cool.

EDIT: never mind about the DC😀

No, for now I just wanna try somthing like this:

draw it even more basic and you'll see that it will not work

edit: observe difference between your schm and DeHaan's

hm ....... I just woke up , and will continue to sleep soon , so forgive me for little fluffyness ..... it will work , but you need cap for bootstrapping of TL and - of course - that's entirely buffer amp , same as F4 ........ unless Lundahl isn't connected with some gain

too sleepy to search

edit edit : connected as 1:5,6

flg. Your schemo does not show feedback; like WimdeHaan's. Did you build it and/or plan to?

Feedback? What Feedback? We don't need no stinking Feedback 😉 [Why bother with feedback when its objective and subjective performance are fully satisfactory {to you and others} without it?]

buzzforb may be blown away and speechless!

yup

buzzin' around as happy monoBee



(mono as totally happy , even if his bstrd is stereo)

 

[Antoinel]

if , and when .

ZM: I hope that flg will consider listening to his build with and without feedback. His findings will and can only be valuable.

 

[Antoinel]

yup

(mono as totally happy , even if his bstrd [Franken6; revived and infused with new tech gadgets] is stereo)

Got mine finished around 10pm with kids already in bed, so no chance to listen. Headed out of town at 4am this morning for the week which kills my activities for a while.

I am eagerly awaiting your results. 😎

My PCBs are due for delivery on Friday, at which point I can complete my stereo build and do some serious listening. 🙂
