The books I have don't get very specific about discrete shunt regulators.

BDP
I'm not sure that I understand question ;


btw - those books you have are then good for nutin' ..........

ok - look just at positive side of Shunty :

CCS made of Q2/Q3 is pushing current set by 0V65/R7 = 140mA

Pumpkin will eat ,spend ,waste, whatever you like - around 80mA of that PUSHED current

rest of 140mA is spent,wasted,shunted ,eaten,whatever you like - with Q11.........because Pumpkinlike stage preceding Q11 is measuring voltage at output ....... and telling to Q11 to keep it at 36V above ground


'nuff?
