B&ok pro10 mc refurb help


What caps can I use? May I use Teflon comparable caps, ?
anything else I can replace in this preamp? Had for well over 20 years, still sounds very accurate, would like another 20 years with it.    

Everyones hel help is appreciated. 

What at about a new vol pot? Also possible?  

Please help, will be sending to sounds Classic in Rockford for the work.
