sorry Wakabi!
For all the other:
- I will connect only +60VDC (text in red) and not the max. possible plate voltage of the 1AD4 for the desired voltage swing of 32V and a constant current of 1mA: for Wakabi, + at X111-1 and - at X111-2,
- therefore I need only 2 LT3092: N111 ist NE Not Equipped and bypassed by an 0R resistor (MMA or MINIMELF will fit SOD80C V111),
- the regulator will accept up the +45VDC but I will connect only one lithium battery: for Wakabi, + at X3-1 and - at X3-2, oups, perhaps a schottky on the plus pole? What do you mean Wakabi?
The blue values are the max. values, the red one for my first tests.
For the tests: +60VDC and 2 CCS in serie (experimentation needed with R113 - R116) for the plate; +3VDC lithium supply and DC/DC for +1,25VDC for the heating; BUF634 powered bei +/-18VDC.
