It's possible that line out to the 386 there is the wrong point. If it is try the neighbouring ones as it will be one of them. Hope this proves of some use to anyone wanting to do the sequencer mod on a smaller dd though. Fitting it to a midi enabled machine is obviously a waste of time but it's a good mod for the basic ones with little control beyond preset rhythms and being hit.
Oh sweet! I think I mostly understand all that. I'm looking at the
LM386 diagram on Futurlec and a lot of it makes sense.
Where I'm really murky is:
1) I'm assuming when you say 'all vero tracks under 386 are cut' it's the lines on the perf board you're referring to, not the actual PCB. In other words: None of the 8 pins on the 386 hook to each other or anything else. Correct?
2) On your diagram between what two points would you insert caps to experiment with the distortion sound? If I had to guess I'd say it would be bridging pins 3 + 4 on the input, or 5 + 6 on the output. Am I close?
3) This is the most important one: Since I don't have a suitable DD yet I wanted to wire this distortion into a toy keytar I'm working on (I found 22 extra notes & an extra drum beat with 4 extra fills!!!). Do you think I'd be able to do this the same way? For example, could I just wire the line out from the speaker terminal to the 386/DPDT, etc?
