After narrowing this to three suspect components, c178 (2.5uF 64v electrolytic) was found to have over 2k resistance both ways. It is located at the output of the EQ preamp, at the emitter of Q120 to be precise. Machine now seems to work normally. One or two minor adjustments still needed to get it to full health.

Thanks for the interest!
