I have SSHV2 completed but still outside the Psu box, for an easy further fine adjust if in need. First listening was completed, and results exceed far above my expectations. Is been an overall improvement, I can't point on anything in particular, detail, imaging, scale or extension of extremes..etc.. everything has pushed up togheter to another level of performance!
Setings on SSHV2 are most less Vin to vout possible, I succed 77 Vout by only 83Vin in order to keep heat low. What a wonderful design it is.

Pic below is the field coil speaker. One channel loaded already. Is top of the range, (100% handcrafted) Super Aero series. I was aware from the luthier themselve Mr. Oleg Rullit, do no add any regulator and keep the power supply simple. But proven not to be the case when using SSHV2.
Thanks so much for kind attention here, euro21, Salas, and Felipe for encouraging me to get out of the shelve this parts, collecting dust for too much years.

Usually the more Vgs (off) a tester measures the more the Idss capability. So when running it develops more Vgs also.
It's only the test to show Vgs.
If you want 170mA, try to use more beefy FET than 100mA capable 01N100.
Hi, Felipe is noticed already I got SSHV2 again at half the current. Really appreciate assistance here.
-Based on settings:
*Vin = 95Vdc
*R4 = 0R
*Rload= 500R
-I measure readings:
T.P.= 94mA. (not reach 170mA)
Vout= 42VDC (not reach 77Vdc.)
Q1 Vds.= 96Vdc
Q1 Vgs.= 1,4Vdc
Q2 Vds.= 1,4Vdc
Q2 Vgs.= 0,1Vdc

I completed another board, same settings, including Q1 DN2540, and Q2 IXTP02N50D.
It measures very close results 88mA/40Vdc.
So I concluded the two boards are healty, and just the desing can't reach my demands.
Silly as it can be, I achieved better specs yesterday when Q1 was lose sitting on their row pins shoket, or later when same Q1 was cold soldered.
