Capacitors in Cary PH302 phono amp

I've just bought a S/H Cary PH302 mk-2 phono amp.
I noticed that the 2 caps near front tubes, C15 & C16, appear to be different to the caps shown in the pictures on the Cary website.
Upon closer inspection it appears that these may have been changed by a previous owner. See pic below:

The substituted caps(?) are Multicap PPMFX types, 1.0uF/200V.
I found a capacitor test that rates these caps very poorly.
My question is what were the original capacitor types and value.
Any suggestions for substitution, other than original?

A closer look at the cap to tube distance after a little tweak to the left:

Tobes,

I would buy a roll of automotive gasket material (the grey multi-ply sheet) Cut a square and stand it up between the capacitor and tube. In a tube cd player mod that I installed Mundorf caps close to the tubes. The gasket material blocked the heat. Without the gasket material, just too hot for the long term.

Hi Tobes - we must sound like a bunch of old women with our comments. Next step if you want to go further would be to replace any Solen's in the signal path. Even the MIT will easily surpass these in speed, timing, dynamics and your pre will just get better and better.

+1 to the above post.
Also,

To the left of the Mundorf appears to be a Cary "Audio One" oil capacitor (the long silver cap). That has to go, along with the Solens that are probably bypassing the nearby electrolytic caps.

Reb, Dover - what type of cap would you suggest to replace the .22uF 600V cap (long silver one in the PSU)? - I'd need something with similar form factor due to proximity to the Mundorf and the electolytic on the left. Could a bypass be used here?
Likewise what would you suggest to replace the Solen caps?
