wildcat sample and hold

[vladosh]

having a bit of trouble building a Rene Schmitz sample and hold i thought i 'd try a simpler design i hope this one will work so i just thought i'd share the stripboard layout .. not sure if i can replace the 2n3819 with bf245c if anyone got a clue it would be nice .. this layout is with the mods yusynth did .. it's from his wildcat page ..

it is this one , http://yusynth.net/Wildcat/sandh-module.html , right? That's a really low parts module.

Btw. I think you could remove the shortest wire going to the Collector of the 3819 if you make the wire on the left side one hole shorter.

Yes ,that's the one ..and thanks for the tip . Still not sure if i can replace with bf245c i can find those ..

I looked at the data sheets and it seems to me that you could replace with the bf245c; you might need to tweak some of the input/output values though, im not sure. Most of the specs were very close.

i found that 2n38129 so i haven't tried with bf245c .. anyway a simpler s/h which i build and it works but you may wanna check the layout if your building it .. it's from Osamu Hoshuyama design

Hi Citric , i used 6v regulators which i think now must had output a bit less then exact 6 v so you can try it
