So far, most "sources" for BA662A chips that have been found online have not panned out. If you're convinced that you really need one ([[ChairmanMeow|I]] used one and don't hear any positive difference), your best bet is probably to gut one from a dead or cheap synth that contains one.

=== Boss HC-2 Hand Clapper ===

http://www.sonicstate.com/synth/boss_hc-2.cfm

This little analogue hand clap synth is in a stompbox formfactor. It has a piezo sensor and a trigger input. It makes a clap sound. That's it. If you can find one of these cheap, it's a good candidate for ripping the BA662A out.
//I do not recommend to kill your HC-2, it is in fact the single best and most versatile handclap out there!!  --- //[[creekree@gmx.de|Creekree]] 2007/09/20 14:45////

=== Boss PC-2 Percussion Synth ===

http://www.sonicstate.com/synth/boss_pc-2.cfm

Like the HC-2, this little stompbox has a piezo sensor and trigger input. Unlike the HC-2, it's actually a very cool little synth that makes modular-ish decaying analogue bloops and blips. Rip the VCA chip out of a dead one, and if you must gut a live one, at least replace it with the BA6110 so the synth still works.

=== Roland TB-303 ===

If you can find one of these flimsy silver plastic synths, by all means gut the chip out of it. In fact, there's a good chance it may have a couple other useful parts inside. This thing is so old, and doesn't sound //anything// like a real bass player - I can't see any reason not to gut it for parts. Sorry, I can't find a link or photo of this dinosaur, you're on your own here.

=== Juno? Jupiter? Where else? ===

...
**PLEASE** keep in mind that taking a BA662 out of any of the listed devices will render them useless unless you ressurect them with a BA6110 //which is not a direct replacement//.
