MOTM

I've recently added Ken Stone's CGS63 power supply delay board to one 
of my MOTM synth cabinets. I'm happy to report that it has completely 
cured the startup problems I was having with that cabinet. I will be 
adding the CGS63 to all remaining cabinets and can highly recommend 
it to anyone else who is having power supply startup issues.

I'm posting this message to the MOTM list because I've had a few MOTM 
users ask me for a parts list.

Note that the CGS63 will accommodate +/-15V alone, or +/-15V and +5V. 
I built the full circuit with support for +/-15V and +5V. Here is a 
Mouser parts list for the full circuit:

Quantity	Mouser#			Desc.
1		512-1N4002		1N4002 diode
1		512-BC338		NPN transistor
1		511-UA741CN		741 op-amp
8		571-6404456		MTA-156 6-pin header
2		653-G6A-274P-DC12	12V relay
1		72-T20YP-500K		500K trimmer
1		291-47K-RC		47 kohm resistor
1		291-10K-RC		10 kohm resistor
1		291-1M-RC		1 Mohm resistor
1		291-100-RC		100 ohm resistor (RCO on CGS63)
1		140-XRL25V1.0-RC	1 uF capacitor

If you don't need +5V at all, and you're sure you never will, then 
use this Mouser parts list:

Quantity	Mouser#			Desc.
1		512-1N4002		1N4002 diode
1		512-BC338		NPN transistor
1		511-UA741CN		741 op-amp
8		571-6404454		MTA-156 4-pin header
1		653-G6A-274P-DC12	12V relay
1		72-T20YP-500K		500K trimmer
1		291-47K-RC		47 kohm resistor
1		291-10K-RC		10 kohm resistor
1		291-1M-RC		1 Mohm resistor
1		291-200-RC		200 ohm resistor (RCO on CGS63)
1		140-XRL25V1.0-RC	1 uF capacitor

It is possible to add the +5V support later, but it would be a pain 
to upgrade, so make sure you make the right choice.

For some reason, the 100K trimmer is "obsolete" at Mouser. You can 
use any trimmer from 50K to 1M. I've listed the part number for a 
500K trimmer, which is what I used.
