Sons of VHex

I've done a little more testing on the VHex+CP amp. Great running and great sounding as always! it has a very slight turn on thump, but noise free otherwise. Here's some scope shots.

Hi,
i still follow, stumble behind. :)
Thanks for advise Valery- i have tested a bit the many options you have to
create pattern- diptrace is very comfortable, but makes smoking my head to
find something out- if you found its clear- it's fun but needs much time for me,
will go on. :D
Nice job Jeff- you presenting a finally working Son. :p

What sre you having problems figuring out in Diptrace?
 
Constant Power approach in the front-end

VHex+CP is an excellent amplifier - simple enough, easy to repeat - with the good parts and no mistakes it will start working from the first power on, minimized memory distortion, low THD / IMD, inexpensive, unconditionally stable, highly reliable, no hum, no hiss - dead silent with no signal, clean soft symmetric clipping. Punchy bass, natural highs.

Many options for input jFETs: 2sk117, 2sk170, 2sk209, 2sk150, BF862.

Initial testing by Thimios, reference build by Jeff, Terry is going to build it as well. Slightly updated front-end from this amp will be used is the high-end ultra-low-distortion monster-monoblocks.

Through-hole and SMD boards available.
If you're looking for an easy-to-build no-problem high-quality amp with around 100W @ 8 ohm power rating - that's the one! ;)

Cheers,
Valery
