Is this cascode diff amp properly biased? Output is single ended between Q3 and Q5. Is it supposed to be DC biased so high though? With 24k resistors instead of the active load formed by Q4 and Q5 I was able to get the output bias voltage to (VCC+Vtail)/2 (or about 13.5V) but I can't do it any more.
