Note: I measured the above module today...the board extends 3.875 inches behind the panel. That's pretty deep for most Euro racks...make sure it fits before you order! |
Clarke,
Which pots and jacks did you use? I want to make sure the ones I order are a good fit for the panel. I've put together a Mouser order for everything except pots, jacks, and vactrols, and I'm hoping I can get all those things from Smallbear. Thanks!

Pots - Alpha 16mm Potentiometer. PC Mount for the Offset & Resonance, doesn't matter for the CV attenuator (solder lug would be a bit easier):
SmallBear - 1010A
Even cheaper at Tayda
Jacks - Kobiconn 3.5mm Phone Connectors
Mouser - 16PJ138 |

Thanks! Would this jack at Smallbear work, too?

| I'm not sure, but I would guess not. The input jacks on this are really close together...I can measure it when I get home. If you buy them and they don't fit you'll surely use them eventually in another project...those look like nice jacks. |

Hi Clarke / All
I'm trying to get my head around a BOM for this project in Euro that relates specifically to builds Clarke's Faceplate ; as is.
This is a .xls of what Thomas had suggest in his Rev. 3.2 .pdf of the board.
PLEASE NOTE !! This .xls is based on building 4 x PCB's for two separate Dual LPG units ; please divide component counts to suit your own project.
Vactrols used in this BOM are the VTL5C3/2 Dual Vactrol. It's really your choice on how you go with these.
Could you give these the once over Clarke ?
Maybe it's time for a build thread for this Euro Version...

It's been a while since I built mine, so I'll just cover the things that pertain to the panel, and anything else that stands out. You don't have to buy these parts at these places, but you can use the names to search for them anywhere you want.
The part, "What is this called?" is a Shrouded Header 10 Position 2.54mm
Use these to make a power cable: 16-pin (power end), 10-pin (PCB end)
My panel doesn't support the Deep Switch mod, so you don't need that switch.
My panel does support the Resonance mod, so definitely get the resistor & pot for that. When I built mine, I used the part substitutions that Dave Brown talks about in his build notes. They're not working for me, it's something I'm looking forward to changing when I "move in" to the new panels.
The 3PDT Mode switch is not optional, it's how you select between pure VCA, filter, and "both" modes. The resonance only works when the switch is in filter mode, which is indicated by the graphics on the panel. As long as you use a 3PDT, you'll have "both" mode even though it's not indicated on the panel. The panel is designed to fit the switch that Thomas White recommends in his BOM. It's tight but it fits, and it's a quality switch.
You don't need Ebay to find 3.9V zener diodes, the have them a lot of places, including Tayda.
Allied has a little better price on Dual Vactrols than Bridechamber.
14-pin IC sockets are available just about anywhere.
Hope that helps! |

I think this is good ribbon cable for the power cable. Is it easier to just solder individual wires to those headers to make the power cables?

The 10- and 16-pin IDT cable mounts I link to above are way easier than soldering...you clamp them over the ribbon cable and you're done. |

It's actually meant to be a CV attenuator...you wire it between the CV input jack and the CV & Ground pads on the PCB, like this:
(I hope Fonik doesn't mind my linking to his diagram)
There is also a way to make it in to an attenuverter, I'm going to ask Negativspace to post instructions on how to do it. |

Tayda only carries the 3.9V 1W Zeners.  |
1W Zeners are fine. That's actually what Thomas White links to in his BOM, I don't know why he has them labeled as 0.5W in the spreadsheet.
Generally speaking, going with a higher rated component is fine electrically...going lower may cause problems. The only thing you'll want to check with a higher rated component is that sometimes they're larger and may be a tight fit on the board. |

FWIW the substitutions to accommodate 100k pots in Dave Brown's build would not have been for quality reasons but because MOTM'ers have a limited selection of affordable values available in those cwazy cermet/plastic pots they love so much. Anyone using Alphas might as well stick to the values in Thomas's schematic.

This would be awesome if I need need to change anything before I send my order off to mouser.
Anyone else found anything useful and well priced at Allie other than the vactrols? I hate to pay shipping on a couple vactrols. |
