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?

Tobes, I wouldn't lose too much sleep. My Marantz 7 still uses the original MIT caps I put in 10 years ago and it has seen off my ARC and Jadis preamps quite handily. The 3 caps you mention are all well regarded, what I know from experience is that both the RTX and Mundorf maintain the very good timing of the MIT PP... just read heaps and go with your gut instinct. You can always put the current caps back in if you dont like the result.
Ok, I've ordered both the RTX and the Mundorf Silver/Oil - that way I can experiment and it won't cost me the earth.

Thanks for all the helpful input.
Tobes - good luck and let us know how it goes. Will be interested in what you think, as it may be time to give my preamp a birthday as well.
Tobes,

The RTX at 1uf is physically a large capacitor and IME the larger value RTX caps tend to have a noticeable bass overhang. RTX is best used IMO in smaller values ie .15UF-.22uf as bypass capacitors. Your best of using the Mundorf full range and changing the order for the RTX to .15UF and using that as a bypass.
