Hello Shaan
here is my interpretation of your Peeceebee V4
2x24v 250va and 70000µF for each I know it's too much but I had them in the drawers!
it is true that the mod rev1 lacked bass but it had a beautiful sound image, silky and nervous at the same time
the rev2 with 47p, 220p is better it has lost nothing of its silky nervous image but with the bass and more in the face it's good and also a little too much for my ears, for my taste.
on your advice today I change 68p, 330p and I will listen like this while expecting new 47p, 220p of good cality mica to make the difference, but anyway I am happy with this new amp, even at low volune it loses nothing of its musical quality that's what I ask for a good amp
thank you Mr. Shaan, see you soon

My pleasure. It makes me very happy to know you liked V4's sonics.

On your behalf. Hope you don't mind. The build is simply extraordinary! Do send me more pictures via facebook in case you're still facing problem uploading them.

Super !
Merci beaucoup Shaan

You should be very proud of that beautiful build. I hope it sounds as good as it looks.

... what the hell ... the new power plant for the ISS with a sound feature ...
I love it ...

4 channel amplifier ready to go! Heatsinks are cold at 20mA, maybe I'll crank it up a little bit...

Very nice. Reminds of my 4 channel attempt early this year. Mine was all sorts of mixup though, and with internal heatsinks getting modest airflow from the holes in the floor.

THD 100Hz 10W - 0.0005%, 1KHz 10W - 0.001%, 10KHz 10W - 0.002%

is there any LTspice files for distortion sims on this thread?

 

[shaan]

@ctrlx
No. These are measured results.

 

[ctrlx]

with my sims i get 0.03% for 10KHz at 10w into 8ohm

 

[shaan]

Okay. Looks like something is wrong or missing.
This is a GB thread so kindly open a new thread where you may get help with the simulation.
Thanks

Any current alternatives for the 2SK1058 and SJ162 MOSFETS? Here in the US they are difficult to find.

Thanks

 

[gwrskien]

You can use theese from Profusion i belive..

ECX10N20
ECX10P20

ECX10N20
ECX10P20 are indeed a great replacement , but if you want you could contact :

You can use the Exicon ones as others have suggested. If you need the 2SK/J ones let me know.

 

[asuslover]

Sorry Shaan , he asked for someone from US, that’s why I recommended Jack.

 

[shaan]

I get it! No need to say sorry.

After a year of blackout I have been getting the mosfets again, so just letting everyone know.

Shaan is there 2 pcb`s + mosfet left for me?
