Looks like there are 3 versions of pots Colin sells.  Which one are you guys using?

OM-01-028 or RU-01-022 or OM-01-029?

UPDATE:
This is the one Marc recommends.

Also, for the bypass switch is it AL-03-001 or AL-03-002?  I'm honestly not sure if it matters as long as they are 2 POL and latching.

Thanks

I think it's this one:
OM-01-028 - 16mm - 2 gang 47k rev. log
Part Code: OM-01-028
It's listed as 50k LIN in the BOM, but from what I know a rev.log works better in this application.

I'm also wondering wich switch to use. Is it this one ?:
AL-03-002 - 2 Pole Changeover Switch (PCB Mount) - Latching Miniature
Part Code: AL-03-002 ??

Ok, thanks! (Don't know about that switch)

 

[Marcocet]

Yep. Dual 47k or 50k rev log. The board is sized for: http://www.audiomaintenance.com/acatalog/om-01-028_extended_info.html

 

[TapeOpAl]

Anyone know the current draw per board? I have a lot of newbie questions btw

Thanks!

 

[dandeurloo]

marc, which switch did you use for the bypass?

The pins didn't QUITE line up, but with a little squeeze they fit fine.

Colin says the 1/4 shaft pots DO fit on the boards. Would you guys prefer 1/8" or 1/4" shafts? Does it make a difference to anyone? We're gonna have to get some pretty small knobs to be able to grip them anyway. The pots are right up next to each other.

 

[dandeurloo]

no idea on knobs.  It would be nice to use something like on dbx 160's or SSL's.  Something that can have 2 different colored caps.  1 color for the HP and 1 for the LP.  Anyone have a good source?

 

[Marcocet]

We could always do these with inserts: http://classicapi.com/catalog/product_info.php?cPath=23_40&products_id=60

 

[dandeurloo]

Those would work fine.  Right size and we could get a few colored inserts.  Sounds great. 

 

[minor_glitch]

Hey Dan,  you can definitely put me down for one of these cases, along with a prr176 case whenever those are finished up!

 

[Marcocet]

I'm an idiot, those pots have 4mm shafts, not 1/8". I don't think those knobs are going to fit. Maybe it does make more sense to move to the larger shaft size....

Working on it.

 

[G-Sun]

What's the current draw of the boards?

 

[jensenmann]

20mA

 

[Marcocet]

Beat me to it Jens

Okay, I think it's a wise move to switch to 20mm pots with 6mm shafts. That way we can use standard 1/4" knobs. The 4mm knobs seem to be damn near impossible to source in the US.

Dan: That will mean the pots are going to have to move slightly on the faceplate. Let me know what info you need and I'll track it down.

 

[G-Sun]

20mA

Thanks!
