It is coming out of the left speaker, once every 30 seconds once warmed up, slower when cool. I've tried swapping and experimenting just about everything. It is not tubes. I had a ticking tube in the old Cary, so that's what I checked first. I swapped all tubes, either outright or L/R, still happens, still on left side.
I will toss this out there, but it is pretty out there... I thought I could hear it but much softer even than normal when the system was shut off, unplugged during a storm. Happened a couple times. Tick coming from same direction as left speaker. Coulda been a coincidence, OR something is still discharging for a while after shutdown.
Could it be a resistor? I have only heard them fail as staticish sound, not ticking. Could it be a cap? Any ideas helpful. It is -40dB or less, so not a big deal except in soft passages. I wanna fix it before I move on to new gear.
Thanks!
