I just imagined a pair of bare Fane 15-300 tc drivers, with one of such amps clamped to the speaker basket (as a heatsink) , lightbulb on top of the speaker, and making music in the bedroom

I had a crazy thought.
Are there any SOT complementary jfet's in current production?
By my paper napkin calculations, you only need .35 Amps.
That would bring down the required number for a follower to ~ 144 per channel, assuming 10 mA Idss.

It might have a higher output Z on the order of 2 Ohms.
But it should have less capacitance to drive.

Might take it from unobtanium to doable.

Hi Mr Michael,
I'm must admit that i'm one of those greedy boys out there who just cant keep their mind off the 120v one in the long nights...

I have just one, i mean just one thing to ask please, as a meditative exercise or pure favour, as my sistem is only 95dB/channel (so not that much to get away with only 1 w), could you please modify the 120vcc version (keep the 120vcc psu) from 1w to somewhere near 5-6w (i wouldnt mind a bit of complexity if it is the case and keep that pure second harmonic signature)?
I would be very gratefull for that, and i think that all of us would be.



Thanks in advance
Sergiu


Ps: can you suggest a more obtainable output part in the same configuration from mouser would be best for everyone i think.

LU1014 is dead end (post #159).
On top of that you need matched devices (post #110).

Wrong thread. This is all about 1W.

But the easiest way to increase power without major change is to go to balanced version.
Something like :

Thank you, you are right.
I'll try the 120v first, as it is, then i'll play abit with the bias... It's too elegant and easy not to try it.
Cheers
