Hello!
Is there a modification that can be done to the SSHV2 regulator so that you can have an output voltage range between - let say - 50 to 100V, or is the only solution to add an anode choke after the regulator?
Regards,
Vidar
Smaller value for the two 68k resistors. About 1/3.

Great! Thank you. Can't wait for the boards to arrive...
IMPORTANT PLEASE READ!!!
OKAY IMPORTANT MESSAGE
It appears likely that I shipped out ~78 2SK117GR's that are of sub-par performance.
Salas and I have tested them and they don't measure exact, but work.
On the scale of the GB, this is a small amount.
All the sub-par units are marked with 2SK117 GR OK.
This will be an eye sight test.
Please inspect your 2SK117GR's for the digits on the flat part of the top.
If you have these units, private message me, and I will replace them as soon as possible.
These are likely only in your BIB mini kits, and if you bought something else, it is not likely but possible. Let me know.
I apologize for this problem, and will take care of it.

Hi dear friend,
I intend to implement in point-point approach the actual Salas SSHV2. It would be very helpfull if I could see photos or schematics of actual boards pcb layout (the two sides of them), please. Let me know if it's possible, I would try two such SSHV2 for my AR SP8 preamplifier clone, please.
Thank you and have a nice day!
Warm regards,
Ion
