Don't be fooled this one has serious balls (capable of 60W into 4 ohms)
Just the first cat skin here. I have a few more cat skins laying around.
Inspiration for this amp comes from The Mu Monster http://www.diyaudio.com/forums/pass-labs/262367-mu-monster.html and BAF Mu Follower.
Thank you Nelson and Star Trek.

Just a quick sim to show it's character
1W into 8 Ohms.
1W into 8 Ohms.
An externally hosted image should be here but it was not working when we last tested it.
It will almost certainly require monoblocks (ie without fans), 200W of heat per channel.
I've got plenty of conrad MF35-151.5 heatsinks. 2 per channel will do the job for me (no fans required).
Fans are definitely a great idea if you don't have the necessary heatsinking for passive cooling.

From memory J2 doesn't double power into 4 Ohms. This is quite a bit different, closer to BAF Mu Follower meets Mu Monster but with Jfet input.
really simple and it is good for me.
the output device is Ixfn50n120sic and the input top is 2SK170 and button is the 2sj74,is that correct,what is the IDDS for the k170 and J74.
One more quesiton,what the current for the output stage,does is support more power output,like 50W at 8 ohms？
Do you still use this AMP for you system.

Hey dumbs, please attach your pictures to the post instead of linking to some external site. I have trouble viewing your pictures.

No, that was just what I used during simulation.
I used 4N25 or 4N35. Just whatever I pulled out of the parts bin.
Got a feeling it was 4N25, but it won't matter.

Not sure what sort of power you're chasing into 8 Ohms, but if it's more than say 35W you will either want to cascode the jfets or use mosfets at the input.
in my thought,50W-100W pure A power,but actually 50W should be fine in my system. Currenly I am woking on Mr.Pass 50W SE power amp,but it has the output capacitor，plan to eliminate it
I would suggest no more than 50W and get speakers you like (or build them - see SLOB) that match it eg 8 Ohms with no crazy impedance dips below 5 Ohms and at least 87dB but preferably 89dB or higher.
