I found the Bourns 50K pots to be a good reasonable solution for the 50K
pots in other Blacet kits I converted.  These are like the one's Paul used
in the EG - blue with plastic shaft.  I could not find the 50K Spectrols
with 1/4 inch shafts anywhere anymore.  Here is a source for some of the
MOTM same parts you may want to use:

	Bourns part # 91A1A-B24-B18 \ufffd 50K linear pots
	Allied part # 754-9418, page 717 

Switches can be found at:

	NKK switch # M2102ES1W01 - SPST  on/on toggle switch
	Allied part # 870-8646 - page 274

	NKK switch # M2103ES1W01 - SPST  on/off/on toggle switch
	Allied part # 870-8647 - page 274

Knobs 

	Newark Part number 57F2348  Alco part number PKES-90B-1/4

LEDs:

	RED:  Digikey # = 67-1155-ND      Lumex number = SSI-LXH387ID
	GREEN:  Digikey # = 67-1156-ND      Lumex number = SSI-LXH387GD
	YELLOW: Digikey # = 67-1157-ND      Lumex number = SSI-LXH387YD

 Everyone has the 112A jacks.

Oh, John ought to speak to that.  The modules I got from him were 15 volt
compatible.

The Blacet connectors will work.  However, they do not lock the same.  You
can change and use the exact one used by Paul.  They fit the Blacet boards
I made.  They are about 11 cents.

	AMP part # 640445-4 MTA-156 post headers for circuit board mounting

Hmmm... Why?  Isn't a Dark star about Chaos?

Can't think of any.

> Connecting the PCB to the MOTM front panel

I used a MOTM bracket (purchased from Paul).  I drilled holes in my Blacet
PCBs in locations not offensive to the circuitry and the drilled holes in
the bracket to match.  I used very nice looking black hex head bolts to
connect the bracket to holes through the front panel.

With no offense intended to ANYone.  NOBODY writes instructions as detailed
and easy to follow as Paul.  I have built kits from PAiA, Blacet, and Big
Briar.  While all instructions were at least adequate (and some better than
others), Paul's were clearly the best.
