Build Your Own Clone Message Board

I realized that I have built 14 screamers for sale, and friends, since the New Year, and I don't have one that works. Let me run down the components on the board, and I'll post progress as I go.



The capacitors are combo of wima's, AVX, and a tropical fish mullard that I had laying around. The The 10 and 47uf electrolyitics are Nichicon, and the 100uf electro is CDE. The Tants are Mallory. The resistors are a combo of Vishay Dale precision metal film, TRW precision metal film, and Allen Bradley carbon comps. Notice I left the diodes out. I have decided on the on-on-on switch for 3 types of clipping. My standard, 2 1N4007's with a 1N4148, 2 red 3mm LED's and the dan-o rat mod dual mosfet/diode config. I think that this should give me 3 different types of clipping, as opposed to many variations on the same themes.
It'll go into a box something like this one that I made for a friend.

looks like nice clean work! i've become a tropical fish junky and have been using them in everything just for that added mojo lol.

got a link for those Mallory tants by chance? .22uf i assume?

I liked that case design back when you first posted it - and I still like it today. Josh must be a really good friend.

That's an awfully big 100uf cap! Why so large for something that's just filtering the power supply? Will it fit in that case OK?

Another, possibly silly, question: Does twisting the pot wires make a difference when it's running inside the (shielded) case?

Robert

The case that Geek is using will more than accommodate.

Geek! Very cool!!

Sorry Mike, bought out the supply from a friend. I have some pretty brown low voltage jobbies too...don't know who made'em




Thanks. Josh is a friend from the old days, and has been a "supporter of the arts". He deserves an award. I made another 2 like this for friends as well. Payback is a bitch, but I am not.



Barely. It's 100v, but, it's CDE so...



True.



Thanks Toney. So, I ended up putting my diode configs on a 12 position rotary, and It's not working! The diodes are lifted, and i'm not getting in. I tried everything, and now the rotary is living outside of the enclosure with 2 long wires so I can look. I have those 2 wires into the smaller diode pads on the board. I have tried reversing the direction of them, nothing works. must be the sloppy soldering job on the rotary...it was getting late by the time I got to it. Used up all of my 1N914'a....can I replace those with a 1N4148? I have 800 of those....

Not my project, so I don't know, but I would imagine it would make running them a little easier. It seemed to when I was making synth modules... although that wasn't is such a small / cramped space as a stompbox.
