Okay I took a bunch of measurements.

Q1 B = .6V C = 5.79V
Q2 E = .6V C = -33V
Q3 E = .6V C = -34V
Q4 C = -34V E = -34V B = -34V
Q5 -27V at CR1
Q6 -27V at CR2
Q7 B = -26V E = -26V C = -144mV
Q8 B = -26V E = -26V C = -26V
Q9 B = 7V E = 7V
CR10 E = 7V
Q11 B = 9V E = 9V C = 43V
Q12 B = 9V E = 8.62V C = 43V
Q13 B = 8.62V E = 8.5V C = 9.68V
Q14 B = -.6V C = -9.2V
Q15 B = -8.5V E = -9.2V C = -42V
Q16 B = -41V E = -41V C = -8V
Q17 B = -8.5V E = -8.5V C = -9V
Q18 B = -26V E = -26V C = 42V
Q19 B = -42V E = -42V C = -26V


Q4 and Q12 stood out as having funny values compared to how I was reading the schematic.
