ba662 tall clown arrives

clown comparison

Having given up trying to hand solder the SOT-363 bits on the OpenMusicLabs BA662 clone/clown, here’s a version with BCM847DS/BCM857DS transistors instead of the dust-like PMP4201/5201.

No idea if it’ll work. The specs look almost identical, apart from a tighter hfe tolerance on the smaller device which I don’t think will matter anyway.

    How did you get on with the tall clown?

    Think it works but I’ve cleverly managed to break my collarbone in the meantime. When I’m properly back to two arms I’ll have more of a chance.
