The connection marked 33 is the output, which is connected to the emitter, so from top to bottom, the pins are C, B, and E:

The emitter is the pin closest to the tab.

This matches the 10k and 330k resistor values in the schematics as well, even if not everything matches exactly (the stripboard doesn’t have the diode, the schematics has no 1M resistor to −12V what I can see).
