Who did the Supa Sustain?

[Thomas P.]

Did anyone build it? I would be really interessted in how it worked out.

Yes I tried to build a working Supa Suatain
  But No it didn't werl///dont be discouraged by my failures though

I built one that works. It was some time ago but IIRC I had to fiddle with the LED/LDR combo a bit to get it working. Try a high efficiency LED and an LDR that goes to a fairly low resistance.

What transistors did you use? The schematic says BC169B but they're quite hard to find for me. I wonder if the ordinary 2N3904 etc. will work, too?

I don't remember exactly what transistors I used. Probably 2N3904. Most projects that use bipolar transistors will work with a variety of subs. They might not sound exactly the same as with the originals but they will work.

I don't think there's anything particularly special about the BC169B, Small Bear does have them if you really one to use it.  The layout on my site is designed for the modern common transistor pin out like the 2N3904.

Well, ordering 4 trannies form small bear to europe seems a bit too much for me...I designed my layout for ordinary pinout, too :wink:
I will use sockets and try a few types and see what's best.

Thanks for the fast replies
