Alrighty,...again once more

Voltage Regulators U14, 15, 16, 17 all test correctly.

Q18 (transistor) 32vdc regulator, I read 38vdc the collector, 32.4vdc on the base, and nearly nothing on the emitter.

Diodes 2, 3, 4 and 5 all test good. D3 / R133 junction should read 23vdc but there is nothing there.

The path between the emitter and J-5 is good, 0 ohms, no open ckt.

Now, why don't have anything on the emitter? I could pull Q18 and check it, but rather know for sure before pulling the bottom off as well.

Either way I don't have that transistor in stock so to speak, so I'd be ordering it and I'd rather make sure I order everything I need at once instead of willy-nilly.

Sorry Cohibaman regarding the previous post ,.. I meant to delete it and not post it, but this one instead
