Salas I only get max. 30mA CCS with 150VAC tx, what's the possible issue? I use CCS 30mA as load, also I use 100R 100uF to split B+ for both channels. R9 & R10 both are 56K in place of both 68K. The SSHV2 CCS works well to max. 30mA, I tried to lower the CCS load to 20mA but the same problem SSHV2 max. CCS 30mA.

Is the transistor next to it ok?
BJTs KSA1381
Q4 seems OK Vbe 0.6V
Q5 seems gone Vbe 0.05V
There is a way to measure the JFET Q6 & the mosfet Q3 to know if are OK or not?
Was Q5. Now can set the SSHV2 CCS to 50mA & adjust Vout but I have a problem CCS load can reach 15mA each channel, only one channel 13.5mA max. and the other 11.1mA. CCS load tested without SSHV2 & reach both channels 15mA each, attached CCS schematic used.

what do you think about using something like this to get raw 400V dc for the regulator: 3A Rectifier Filter Power Supply Board Audio Amplifier Single 18V AC-DC Convert | eBay Of course changing all component for proper voltages? Space is tight, so looking for something small...
Caps not absolutely necessary, try with just resistors
The issue continue without 100uF caps.
