How to replace volume pot in Dynaco Pas

Ralph would be the expert on caps, for sure. I can say that I don't like the sound of orange drops, but there are really nice caps in all price ranges. For $1 to $2 there are the polypropylene and tin foil Daytons from Parts Express, which are surprisingly nice. Some like the Solens as well. For $5-$6 the Russian K40 caps are fantastic but a bit larger than many other caps. The sky is pretty much the limit from there if you have the budget.

Oh, I am sorry, for the caps that define the RIAA time constants you will need small value caps. The caps that I recommended above are large value coupling caps. I wanted polystyrene for these small values and had a heck of a time finding a suitable vendor. Google "Just Radios", they are a husband and wife team in Canada, the prices were fantastic, the polystyrene caps sound great and service was awesome. Be careful though, polystyrene caps are more sensitive to heat than other compositions so a variable temperature iron or a still, quick hand will help here.

I bought a kit for my hafler and most of the caps were Daytons. The amp sounds better than new.
I am curious about the russian oil and paper.

There is not that much on these boards, so I imagine it is pretty cheap to recap.
How about the resistors?

Resistors are dirt cheap, most use metal film, but some prefer carbon. There are many Dayton branded caps, but unless you need high values, the only ones that I would use are the tin foil jobs. The Russian K40, not K42, can be purchased direct from Mother Russia on ebay, just check the dimensions first.

Regarding the Dynaco Doctor image: is this mod to bring the RIAA curve closer to spec?

As for the caps: what voltage should the phono board caps be?
I am thinking of doing the Dayton foil caps.Good price and easy (1 day) delivery.
