New xa.5 series amps

[Nelson Pass]

some of them (including me) are enough brave (read -silly) to took challenge to build multi monsters with at least 150-200W heaters

I believe that is on the Burning Amp agenda. The F6 will still fit
in a regular FW chassis, and I'm planning on building maybe 10 of
those.

spiffed up version of F2?

 

[Nelson Pass]

Really?

Actually I have a couple of candidates. Feel free to express your
preferences.

 

[MEGA_amp]

Just wondering. You had mentioned in the F2 clone thread about a new version with 1/5th the distortion than orig. I'm going straight to spiffy F2-lite to drive FE127e. I just solder stuff and it makes music, so my preference is for "awesome", whatever that entails...

DIY F6 choice

I would echo an improved version of F2 as a candidate for F6. The concept of transconductance amplifier deserve more DIY attention. I really like the sound of my F2 and would love to see improvements.

No, I would vote for the next generation of F3 as it was promised previously. Pitty that the chassis size can cause definite limitations for the Super Power jFET amp.

 

[elviukai]

my and my friend votes goes to mory powerful variations of f3/f5 in SuSY/balanced versions. I believe we will have soon two diferent brand names- F1 (first watt) and F100(first hundred wats)

F1-5 is like Nelsons babies, while F6-8 will be litle grown up teenagers b

and seriuosly we will wait implemetations with impatience

 

[VladimirK]

Just my dream: FirstWatt F6 Super Power jFET amp in monoblock version, chassis are standard FirstWatt.

I vote for something that is "As Class A As It Gets" with intense control of the speaker even if it only gives me 5 watts of power.

How about something completely different?

I was paper developing something I code named Fe.

All Balanced push pull.
Input transformer phase splitter.
Jfet input. No feedback.
Output on 240:120V Toroidal, driven by source followers.
F3 power supply arrangement.

(thinking aloud) ..... I am wishing for higher power SS SET based on JFET technology with output transformer that our papa Oracle mentioned somewhere in his notes(hopefully it has its technical/ Musically superiority).

Anything, as long as it is even incrementally better than the F5, sonically.

But then I haven't yet built the F5, only for want of the P-channel FET
