Vintage Synth Repair

hey guys...

so i've replaced A1, A2, A3 and Q3 on board b of the Arp Odyssey and
my sample and hold secion still wont modulate anything. any ideas?
should i start replacing caps? diodes? resistors? (all the faders are
brand new so those are fine)


thanks for the help and the interesting discussion on op amp failure
