That's right folks!
I'm <<finally>> going ahead with the production of faceplates for the
ASM-1 project!
(thanks to Stew and others who filled me in on Metalphoto).
The first run will be for 50 (yes, 50!) panels.
Gene has given his blessing on the layout and will be ordering 10 of them
- I'll be keeping 4 for myself, so that leaves plenty for all you
builders out there.
The specifics;
Price per panel: $20-25 (I don't know what shipping costs will be yet)
Time: About 4 weeks
Size: 4 rackspace (7"x19")
Thickness: 1/8" total - .020Metalphoto laminated to .090plate.
Holes: Rackmounting ovals only.
I've done a lot of research during the past week to get the best price.
Prices varied tremendously from one vendor to another - I got quotes as
high as $60/panel and everything in between. I checked with everyplace I
could find on the net as well as a couple of places I found in the Thomas
Register - so you can trust that this is the best price around...
Note that you will not have to do the laminating, it will come that way.
You'll be getting a complete 1/8" panel. I have been assured that this
lamination is just as good (if not better) than solid 1/8" plate. Just as
permanent and better because it's;
a. Cheaper
b. Laterally stiffer
You must drill the holes yourself for the jacks and knobs. There are
cross hairs where each hole should go. The cross hairs are small enough
that they will not show if you use 1/8 jacks.
Panel layout is available via email as a .gif or zipped .bmp file. If
someone would like to put it on their web page, I'd appriciate it because
I do email through Lotus notes and sometime attachments don't come
through for other people.
I will be sending my order in (a check and the disk with the layout)
first thing Monday morning.
I am now taking orders, so reserve your panels quick! I don't need checks
now - just reservations. I will ask for checks when Metalphoto says
they're ready to ship the panels - that way I can send your orders out as
soon as the panels arrive...

The panel specifics are as follows;
All knobs are at least 1.4" center to center.
At least .75" boarder between the sides and the first knob / jack
At least .25" board between the top/bottom and the first knob/jack
Jack spacing is far enough apart to support 1/4" jacks
Dial markings and style are my own design, kinda modelled after the Serge
stuff

Freq CV Input Jack (scaled)
Audio Input Jack (scaled)
(2) Audio Input Jacks (no scaling)
Audio output jack
VCF Note 1: The output of the VCF as set up in the panel offers a little
more flexibility than the original four output VCF. You have a switch
that when in one position sends the BP output to the output jack, when in
the other position, it selects the output of a linear x-fade between the
LP and HP outputs. The amount of x-fade is controlled by the pot. Notch
output occurs whenever the pot is not panned hard left or right and will
be or less to the HP or LP side depending on it's positon. This requires
a <<slight>> modification to the circuit, but does not require any extra
parts (actually it requires LESS parts).
VCF Note 2: The scaled CV input is drawn as an "inverting scale" - this
means that when centered, the cv has no effect. As you turn the scale to
the left, a positive CV cause will cause the frequency to drop. Turn the
knob to the right and a positive CV will cause the frequency to go up. It
may be possible to do this with no extra parts - Gene and I are going to
look into this. Otherwise, it can definitely be done with the addition of
a single op-amp that can be glued to the back of the panel. We will send
complete instructions. If you don't feel up to it, you could always just
wire this as a regular scaled input and ignore the face plate marking,
until you feel like "enhancing" it.
ADSR (2):
Attack Pot
Decay Pot

Note: there's room for two output jacks so you can put both a banana jack
and a 1/4" (as your final output).
