Well C118 is supposedly to filter transients.
You could of course repace it with a ceramic or mylar cap.

Hello

I now have one HRO-60, which I have wanted since I did not have $800 in
1965, and it has one part that can cause fatal damage.

It is a dual 40 mfd electrolitic between one of the power transformer
windings and ground, and the power transformer is made of unobtanium.

Jim:

The part that will kill your power transformer is C-118, the 0.1 uF
capacitor connected from one side of the high-voltage winding to
ground. When it shorts, your power transformer is history. C-118 has
killed more power transformers in more HRO-60s than shorted filter
capacitors. The line fuse will not protect your transformer. By the
time it blows, the transformer is gone.

My advise it to remove C-118 and do not replace it at all -- it is not
needed.
