Capacitors in Cary PH302 phono amp

Thanks for the replies.
I don't know the type and value of the original cap - hopefully a ph302 owner will volunteer the information.
The input resistance of the my SP16 line stage is 50kohms.

Assuming the value of the substituted Multi-cap is correct - I was considering replacing with a 1uF 200V teflon cap, perhaps the Audience Aura T (they seem to get high praise and not quite as expensive as other teflon caps).

My other train of thought is to put it back to original (if I can find out what that is) - I assume Dennis Had would have tested various caps in that position and settled on his choice for a reason (hopefully because they sounded good).

Tobes, My experience with the original MIT caps you have are they are better than the older Hovland & Auricaps which are vague and murky - so I wouldn't go back to original. The RTX are very good, but word of warning, used in speaker crossover we have found the internal impedance/inductance characteristics were drifting. Discussions with Richard Marsh shed no light on why. We have compared these original MIT in both tube pre and speaker xover to Hovland ( H was murky ), Mundorf Supreme ( MIT had much better timing and around the same transparency - therefore MIT at 1/4 the price is way better value, Mundorf Silver and Oil ( this had much better timing than the Supreme and I would rate it better than the MIT ). My view is go for Mundorf Silver/Oil, Audio Note Copper Foil ( if you dont like silver ), or Teflon. Beware if you go Teflon - they take weeks to run in. Cheap option is go to MIT PPFXS.

Hmm thanks for your thoughts Dover.

Seems that MIT RTX caps are well thought of and regarded as a nice step up from the PPMFX. Economical too.

The Cary certainly sounds ok with the current PPMFX caps, but my feeling is that its not uniformly transparent across the frequency range. The caps may have nothing to do with this of course, but I'm curious to hear what a couple of well regarded Teflon caps might do for the sound. These seem to be universally praised for their transparency.

PPMFX is a very good base value capacitor by itself. Dont believe every shoot out that comes along on the internet. Bypassing that cap with an RTX or Russian FT-1 Teflon gets you excellent sound for little money outlay.

To quote J.C. Morrison from his blog: "cary audio does it like radio shack would have… in the 70′s, if they smoked crank and gambled on tractor pulls". My guess from the Cary products I've seen is that the original caps were Kimber Caps.
