Sub PN3643 with 2N4401 Transistor

[Ken Pachkowsky]

I thought Iread somewhere this could be done? Can anyone verify this?

Yes you can as long as the Collector to Emitter voltage doesn't exceed 40-50 Volts. A sure bet would be an MPSA42, great high voltage general purpose transistor. I got a million of either one in my basement, let me know and I can send you some with a "Canadian Returnee" discount of No charge.l

Now thats funny...

Let me check those specs.....thanks.

Lists Maximums as:

Collector - Emitter Voltage 40

So it should be OK

Turns out I have some MPSA42's as well.
