I also searched for the LT8365 but couldn't find a way to buy it as a part.
I can't wait until next year, so It's expensive, but I bought modules (boards). This is up to + or -280V, so I need to make few changes.

This shop doesn't have an option to ship to the US, so I got help from a friend in JPN.

Made with double sided bread board. HVPS (LT8365) are on the way from JPN.
I planning to divide it into four and stack these in 2 or 4 layers, but I don't think it will be a size that can be called "portable" but I will try...

I am planing to use Toshiba TTC004B instead of KSC2690A.
Cob is lower than KSC2690A (12PF - 19PF) and better hfe linearity.... and I prefer Toshiba rather than KSC/KSA .

Thank you guys,
To save cost for my future DIY projects, I am planning to make a universal power supply.
Toshiba 6RA6 is not easy to find in JPN but we can find imported 9RA6 in US.

JoeMat, Very nice! use LT1021 to the active battery is good idea.
Keven, can you add extra pattern for the solid state input (LSK389 and 2SK170 x2) option?

How is a bias voltage? Too high or low...?
Bias voltage is from a same circuit but if diaphragms have a different tolerance.
