Interest in Professionaly Fabbed Bad Stone Phaser PCBs?

[Scruffie]

Just verified a layout for a Professionaly Fabbed Electro Harmonix Bad Stone Phaser PCB and wondered if there'd be any interest in them for a Project?

The Boards are 4 Layer, Silk Screened, Through Plated and Designed to fit a 1590BB Enclosure with Board Mounted Pots and basically this is just to see if there's actually any interest in them or not before any cash is fronted (Hope this isn't against any rules...?)

Here's the Finished Prototype - The Layout has since been improved aswell to be smaller and clearer...

I might be interested in a couple.  Are the FETs in one of the ICs?

Yeah they're in the 4009 (or an unbuffered  4049 will work as the 4009 is out of production now, thanks to B Tremblay for verifying that)

It removes the need to match the FETs which is nice for a simple build.

Here's the schematic for those interested, the Manual Pot has been omitted http://topopiccione.atspace.com/pjimages/EHBadStone.sch.gif

I'd be interested in one, just to have a backup for my original unit.

Are there any sound clip examples on line?
I'd but a couple boards

This is something I would have difficulty refusing, even though I have more phasers than the original Star Trek series.

Just tell yourself you're doing it for the Vibrato Option

The link isn't working.

But yes this is good idea, I like the sound of the bad stone.
Thats a nice looking board too.
Now if I just had some spare cash...
What are they going to cost?

[oldschoolanalog]

4009's are still readily available. Check it out.

I could be interested. The board looks pretty big. There isn't much room for a battery. Did the original use a battery?

[skiraly017]

Yes please!

[John Lyons]

Yes, two in fact!  and was nearly twice that size.

[soggybag]

From the schematic it looks like runs off 9V. I guess it requires a lot of juice and the batteries are parallel?

[John Lyons]

May have gone through changes with different versions.
