You can do this yourself and just as Stu said,caps are where you can start..To tell the truth,CJ has a nice film cap power supply which is what I do when I rebuild all my vintage amps and preamps for myself and others.
About all you want to change in that PV14 is change some output and interstage coupling caps to Russian paper in oil or a good film and foil or both..You could then put some Schottky diodes in the power supply and resolder the connections on the tube sockets if needed..THat preamp is super the way it is.
