-5.5v between Q,S on Q201 nothing between B,E of Q206 and only about 0.13v between B,E of BC560.Look if Q201,206 show few volts between their G,S pins each. For 206 BJT look for ~0.6V between B,E.
P.S Check BC560 for 0.6V between B,E also.

Change 560, test, then Q201.
Finally i've finished my first BiB....
It will supply a v-dac II.
output 14v
R101 2.7ohm + 3 green leds
Voltage across resistor is 0.90 v
for circa 0.340 ma...
is it good?
I'm using a 18v 60va transformer
mA or A?
How many current draws v-dac II?
Left 100mA more of headroom: 350mA
Current don't change with time, only change the voltage with time.
Cari saluti
Do you think i should change the r101 value?
Thanks ,I don't have any spare BC560's but I have some BC556's so will drop one in and test.Change 560, test, then Q201.
Its time for the output BJT. Shows no Vbe voltage ~0.6V?
OK ,and correct 0 vbe.
