Mixer blues

I found out that there was a last time buy on the SA602/612 mixers in SO last November, heck !

Digi-key does suggest subs:

But look at those prices !  Also, the packaging is unfriendly.

I had thought about re-doing the LF Converter kit for SO when I ran out the the DIP parts in stock but now the kit will be dropped when the parts run out.

I had dropped the SA602 chip from the parts store.   Maybe it is time to do something with those LM389 chips ? :)
