Royer
mic-mod Project
A project brought to you on behalf of David
Royer.
Updated 24 December 2004
but he knows nothing about it yet
General Description
" The Marshall MXL 2001 uses a capsule that is copied from the Neumann
KK67/87 capsule, which was used in the Neumann U-67, U-87, SM-69 and M-269."
With some electronics leaning towards the U-47 but adapted to suit a 5840 tube
and the addition of a Jensen DB/E transformer, Dave has given us some very cool
DIY fun.

To cut a long story short, PCB's were available and then they weren't.
Even so there are people oustide of the US that have difficulty obtaining US
based stick so under a bit pressure and the desire to help out I knocked up
a couple of PCB's for the original project.

A couple of PCB's and a few components, doesn't look that hard does
it ?
As above there was a time when finding the original article was difficult and Tape Op doesn't ship outside the US so I had a rebuild and made the following PDF.
