==========================================

the schematic shows it as a 16-pin chip, with 8 pins used.

pins 1,16 are the coil
pins 4,13 are outputs, L,R (B,A)
pins 6,11 are 2.7K dummy-load
pins 8,9  are inputs

yahoo-groups will destroy any ascii-schematic i do, but if you need more
info, i'll get it to you.

(testing yahoo support of ascii-scematics)

also, i'll see if it mentions it at all, but my guess is that it's just
used to mute the outputs while changing patches, loading data, etc.

for now, bedtime.
