Arion SAD-3 - Rehousing Question About The Foot and Slide Switches

[jasonsguild]

Hi,

I told a friend I'd help him re-house an Arion SAD-3.  The only thing is that I need to gather all the parts ahead of time (due to time restraints), and I will not have the pedal to review the components before re-housing.  From what information I've found, I will need to replace the 1/4" jacks, DC jack, toggle switch and Stomp switch, but I think I can keep the pots if I use some standoffs to position the board correctly.  

Looking at the gut shots I've seen posted, I'm still having a hard time figuring out exactly what type of stomp and toggle switch this thing has.  My guess for the slide switch is that it is a dpdt?  And some kind of momentary switch for the foot stomp, normally open SPST?

Does anyone know exactly what these components are?

Thanks

Looking at the pictures of my SAD-1 (very similar to the SAD-3), it looks like the slide switch is a DPDT type. The schematic appears to indicate a N.O. SPST momentary bypass switch.

Also, the pots used are really more like big trimpots rather than the kind of pots DIY stompbox builders are used to using (like your typical Alpha pots). I would plan on having to replace all the pots and the DC jack as well, in addition to the LED, bypass switch and input/output jacks. Also, two of those pots are reverse log types, not too easy to find.

Honestly, I think that pedal is fine in the plastic enclosure it uses. It's pretty heavy duty, it's not like it's going to break or anything and it takes up less room than a Hammond 1590BB does (if that circuit will even fit in that size enclosure).

Awesome.  Thanks a bunch.  Unfortunately the original case is all busted up, that's why he wants to rehouse the pedal.  You think I would need to replace the pots, even if I just matched the hole line up from the old case and used standoffs to keep the circuit in the right place?

If you get a big enough enclosure you could probably keep the existing pots. I don't think it's going to fit into a 1590BB, but I don't have my SAD-1 in front of me at the moment to verify that.

[jasonsguild]

I'll have to make him measure the existing case to see what room I need. 

I was thinking of tossing it in this guy,A Bit deeper than the 1590.  :  http://www.smallbearelec.com/Detail.bok?no=1072

Anyways, thanks again for your help.

That may work. IIRC the problem is not the depth, it's the length of the PCB.

i have run into several pots of that design that had failed . the shaft cracks at the base , and i also had one that was still in one piece but it spun freely .

if you are going to rehouse it , it may be worth while to spend the extra $$ and replace the pots .

also be careful desoledering everything , i did a dano rehouse and lifted a few tracks , it wasnt too much fun . but you are prolly aware of this .

i had recently (6 months) purchased a few mom stomp switches , i found em for less than 3 @

but i needed a bunch .

good luck !

Yeah, I've had my fun with lifting up a couple pads on a PCB before , so I was hoping to avoid de-soldering as much as possible with this rehouse.  Especially since I think I read somewhere that these pots are really a pain to get out. 

I'll have to check out allect for parts, thanks for the suggestion.  I'll be ordering stuff for my own projects along with this rehouse so shipping wont be a waste.  I usually use SB because they happen to have a pickup location near my neighborhood, which usually means I get the parts a faster than snail mail.  Plus I like to support the small guys when I can.

jasonsguild: Post some pictures when you're done, I'd like to see how that turns out.
