Official M2 schematic

For all the Greedy Boyz,

The M2 officially discontinued, here is the official schematic, assuming that
it has not otherwise been posted.

In particular note the interesting bias circuit that you can use elsewhere.

:cool:

You are extremely generous. Thank you Nelson.
I will stick it on the wall so I can study it.

The value of R6 and R7 seems too large.

Lm385 is a 3 pin device.
Unless one of the legs is shorted then I'm completely lost. Hahaha

Check the Dumbmeter...
 
The Dumbmeter you used to assess yourself must be overdue for calibration.

Yeah, I think I'm out by 2 orders of magnitude. It should 0.02 Picodumbs

Now that I think about it a larger number would make more sense. Less dumb means more smart.
I think I was reading the intelligence meter not the dumb meter. It must be 0.02 PicoSmarts (not very smart).
I'll have a brainwave later and redeem myself for this lack of intelligence.

Ok. If you short out the adjusting pin thing with the negative thing you get a 1.24V reference.
Need to think about that.
