Itchy fingers.....

A good upgrade to psu caps is to simply replace with higher voltage lower esr. I used 450v rubicons. Also coupling caps replaced with high quality polypropylene types of same value. As for resistors, you could try foils in the signal paths. As for valves, Watford valves have stumbled onto a limited stock of Amprex Ecl83's but they cost a bit more than the mullard types. For the diodes, some on here will no doubt have recommendations for their own particular silent ultra fast super dooper favourites.....
