Vintage Synth Repair

Hi,

I tried to repair a Juno-106 by removing the epoxy with acetone on the 80017 chip from the voice that has a resonance  problem, but that did not fix the problem.
I checked the signals with an oscilloscope and I've got no signal coming out of the VCA chip MC5534?
Do these chips go bad as well?
Thank you!

Nicolas
