MOTM

Just some very quick photos of the insides of the rare Moog String Filter.
Quick observations:

a) there are 9 filter cards with 4 filters per card. Each filter has 2
trims.
b) the filter is based on the LM3900 (ack!)
c) The whole thing runs off of +12, no sign of any -12V anywhere.
d) for some reason, the leads are NOT TRIMMED on the bottom of the pc boards
(ack!)
e) no shortage of LockTite at the Moog plant

more to come, this was a 10min breaktime deal.
