SMD LEDs look cool 🙂 I didn't test this version before - tested only an earlier TH one, so this is the first time I see this one running.
Stonehome, use only white heatsink paste. The stuff for CPU heatsinks can be conductive. I lost a few IRF240 in the sx780 over this issue.
Great build Thimios!
Mine is assembled but not yet tested. I'm re-calibrating the NS OPS channel that went bad due to a bad choice of resistors for the drivers. I was told not to use high precision resistors in high current areas since they cannot take abuse and tend to snap quite easily. Bought some 3/4W thick film and installed those. The amplifier seems to be working properly now and I'm just finalizing the last calibrations on that channel.
Thanks

Finally found the time to finish re-calibrating the NS-OPS and everything seems to be fine. I hope I have some time this weekend to fire up some music on it.

Good news Do!
I am in troubles with father's health and i'm out of the game for a little.
Singing!
A wonderful sounding IPS.
I listened for a little but i like this!😎
Test will be later.🙂

Beautiful - many red and blue lights - it's alive! 😀
I like this combination a lot I have also tested it with my TH prototypes about a year ago. Now this is the next level of "technology" 😎

TubSumo
First scope test.
Power Supply+/-50v
Bias 88mA
Offset 0mV.
Picture 3) 1Khz
>> 4) 1Khz clipping
>> 5) 1Khz hard clipping
>> 6) 20Khz clipping
>> 7) 20Khz hard clipping
Amplifier come out of clipping immediately!

Even at 20KHz there's no sign of the rail sticking - mostly because of the very cool VAS configuration. Also, unless you go deep into clipping, the corners are slightly rounded - it clips pretty softly.
Valery yes,i think TubeSumo is one of the best function,even under hard clipping conditions ,IPS.
Evanc,my friend,thank you again.🙂
I have lots of boards in stock. Just contact us through our website and we can hook you up. We have many options to custom tailor the project to your needs so it's best to email us with what you would like to build.

A square wave test.
Looks like a little overcompensated?
