John and Steve are spot on.
You will also learn a lot more if replacing one cap at a time, and noting the results.
Blanket replacement of parts does not teach you anything, and you may end up chasing your tail trying to sort out the man made faults by fitting the wrong part or by disturbing other components and wiring.
I hope you take up Johns generous offer of the meter, don't rely on your faulty Avo.
