ba662

[David Webster]

Hi,
     I'm currently working on an tr808 clone, and hopefully then on to the
tr909 and tb303... I've struct a problem though. I'm up to building the hand
claps and have noticed that they use a BA662. I was wonder how I could
replace this chip with something else or if it could still be purchased???
Also for the opamps in the tr808 I've used LM324's these seem to be working
fine, I was just wonder if these opamps cold be improved on?

Thanks,
                Dave.
