Just wanted to be sure the review was of the newest F6 version since it was also produced with Semisouth JFETs.
This time I did something different... I bought with cash money an F6 from Mark at Reno HiFi.
No solder slinging, no parts roundup, no chassis punching, just unpack the damn thing and plug it in.
Well I did have to take off the lid and see what was inside... had to look at the layout, the wiring, the PC board artwork, the white greasy spots for the 240's...yep, it looked like an amp. Screwed the lid back on and plugged it in. Turned on the DAC (iFi from Thorsten) tuned in the streaming from Classic and Jazz in Paris Hey it works... There is something to be said for ready to play electronics. Not that I haven't bought ready made stuff before but amps and speakers are what I like to build.
Ill cut to the chase cause I'm hungry and Christine has breakfast ready... (she said something about homebrew scones)
This is one very seriously great amp... No ****!
Im about to pull out my Feastrex speakers and let the F6 put the spurs in that driver. Yikes folks this is one fine machine.
Hunger... food ... scones...

Well it was Semi South vs Enzo Ferrari... and look who won.
Oh and By the way or BTW...
I forgot "Bad words" are stricken from the posts... One can not type words like XXXX or XXXX or XXXX.
GRAB...generally recognized as bad.
Anyway breakfast was stunning... Scones good.
Looks like I'm gonna have to build an F6 for my wife... She came in my room/shop/lab/shack yesterday and started crying. yeah, the F6 is really good.

Hi,
I changed the C1 & C2 to high quality caps and the still in one channel there is a big swing on my fullranger cone at the time of power-on and then it settles in. There is no such behaviour in the other channel.
I don't know if my fullranger is going to get damaged with such a huge cone suck out in the beginning.
I am completely out of depth to trouble shoot this problem. Need some help here.
Thanks in advance.
Cheers.
I built a system for a women here in Santa Fe a few years ago using the 9Dnf and the Eminence 4015...OB... Using your Pass Labs 30.5 to drive the whole thing... Wow!
I have the 5Dnf (the cheap ones) and plan to put back into service.
Also those Lowthers with the field coils... (The ones Dave wound) Those drivers made their way back to New Mexico. The deal was, I got the drivers after Dave, Jon and god knows who fooled with them. I bought the raw drivers from Jon and handed them over to Robert who machined them up at the lab in Los Alamos... Your tax dollars going to something good.
Anyway the 5Dnf and the 4015 should really be happy with the F6... I love that sweet midrange of the Feastrex. Wonder what happened to those guys? (Feaster that is?)
Ill get to it next week.... right...

Some kind soul on this forum pointed out that this could be do with gate stopper resistors and parasitic oscillation at the time of start up and he also pointed out to Papa's talk in BAF during the F6 discussion. Will pursue that line and check.
Thanks.
