Hmmm. I've tried to restore a number of pieces of
vintage gear, including a Citation One preamp. I was
told by everybody that these multi-section caps aren't
available any more. Do you have a source?

As a rule people gut the old capacitor case and conceal
a collection of modern capacitors inside of it.
Capacitors have shrunk enough that this is generally
very easy to do, and results in an equal-or-better end
product. For example one of my friends did this with a
pair of MacIntosh 75 watt tubed amps.

I'm finding this quite baffling. What is the point of
replacing a multi-section cap with another one? Can't
you just put a single- section cap in its place, or is
the problem that the values/ voltages aren't available?

The sections of multi-section capacitors are not usually hooked together
directly. For example one section might be hooked to the cathode of the
rectifier tube, the second to the output of a filter choke, and the third to
a resistor that is part of a decoupling network for a phono preamp.
