This page indicates that the power supply caps.... well the whole power
supply, is less than adequate already. Loosing capacitance will affect the
sound at higher sound levels and not so much low levels or xero levels.
look at the 6th paragraph. I am not suggesting going to the lengths seen
here as it is obvious much more money was already spent just buying 3 of
the delta1010s and other equipment than you wish to spend.
I do remember (from my TV days in the early 80s) watching the monitor CRTs
get a growing moving "blob" that started as a small bump at the top right
of the screen and over a few months would grow to a blob that covered the
top portion of the screen. It was always moving... this was fixed in all
cases by replacing the PS cap. These were electrolytic caps they do wear
out sort of gracefully.
