Simulcast / Broadcast Duo - parts?

[lcipher3]

I know there is a Duo version in the works - I'm sure there is a ton of things in process so not trying to rush anything...
But does anyone have or know the extra pot values and the trimmer values? Would love to know so I can place a parts order and at least get most of the parts (Im sure I have the "other" stuff as I've built the single version).

This one will most likely be released later today, I'll try to get a parts list posted shortly.

One unexpected requirement is a 1590BBM enclosure. The transformer is just a bit too tall for a standard 1590BB.

Hey thanks! - and the transformer is a bit tall.... still, remote mounting (not ideal I know) works.
This is a Simulcast in a 1590B - transformer hiding under the insulated standoff

Still a pretty nice lookin' build! Not very often do I see people using Vishay/Dale "braunschweigers" in their pedals.

Vintange ones at that (1990s) . I have just about every size in boxes of 100 that I scavenged from the scrap heap when we shut down one of our research labs. Partly why I tend to make my pedals look like lab equipment

 

[Ratimus]

That's awesome! I see your pedals that look like lab equipment, and I'll raise you some lab equipment that looks like a pedal.

Slick! VHF stuff - and it goes to 11 too!

Is the 1590BBM a standard offering from Hammond? I don't see it listed on the site though I do see some references to that model when I Google it.

Where did you find those smaller 120u caps? They seem too big everywhere I look.

 

[lcipher3]

heheh - I should have taken a pic - they're 100uF, and on the underside there are 22uF connected in parallel. Total of 122uF.

yeah - you're right. I looked a long time and there just aren't any of the smaller dia 120uF.

Its actually not too bad to off board mount the transformer and fit in a 1590BB

my "Atomic" Doucast - with 1590BB (off board transformer mounting)

I built a simulcast dual into a Gorva Designs S90 from LoveMySwitches, which is near-identical to a 1590BBM but with a rounded lip and a rock-solid powder coat.

Next one is gonna be in a 1950BBM from stompboxparts.com

Thanks for that info Manfesto. Looks like the Hammond 1590BBS has the same dimensions:

That's the size I ordered and they are still too big. Seems like that's a problem everyone has in the pictures I've seen.

I used the 63v ones from tayda and they fit just fine. They are tall and skinny.

Awesome, thanks! I'm going to try those.

 

[Betty Wont]

Awesome, thanks! I'm going to try those.

I should note that they fit fine on the duocast, they would be too big for the simulcast.

Simulcast capacitor voltage ratings

Beyond those indicated to be 35v, what voltage rating do the other caps in the simulcast need to be?

Simulcast 120uf vs 100uf?

Hi all, putting together my shopping cart for a Simulcast build and I'm having trouble sourcing 120uf electrolytic caps in any appropriate voltage, apart from making a whole other order from Mouser for a handful of caps. Is there any harm in using 100u instead? I've already got some on hand...

forum.pedalpcb.com

100uF is a fine replacement.
