Title: Looking for ledgible copy or redraw of Maestro MPF-1 Schematic.
Post by: nelson on November 25, 2010, 07:05:33 AM
Hi folks,

I know there's a re-draw floating around from Bernaddur, all links to it are dead. Factory schematic is illedgible.

Hoping to make a PCB/project.

Anyone save bernarddurs redraw to their hard drives?

Spotted the first Schematic mistake. 22n cap off pin 2 is supposed to go directly to pin 6 of the 4007. Not through the 2M2 resistor.

Easy mistake to make when you're redrawing.

The 2u2 output cap is also orientated in the wrong polarity.

What do you guys think of the general control layout?

I was going for foot controllable pots on the side and having the rotary being foot turnable too. Kind of the same as the original.

Hey nelson,

How goes the layout? I was tempted to make this as my next build and design a fresh layout!? Have you gone for using the original switching techniques or have you changed over to the way xdissent did it here on page 4:
http://www.diystompboxes.com/smfforum/index.php?topic=69871.60

Like the look of your layout so far though!

Any chance of the EAGLE Schematic ;D ;D ;D

Cheers
