BUT, I would think one built on the proper PCB might be ?

Depends on your ears (and ancillary components)! My Aikido with Charcrofts, Mundorf ZNs, and Mills resistors is very comfortably ahead of my modded Pre 3 (with TJS and similar mods). Before that the CF Pre I made with the right and left power supply decoupled also outperformed Pre 3. But Pre 3 is good, and has it's charm. My main issue that led me down the road was its too high gain and also that running its tubes full tilt you get quite a high hiss on the output, compared to silence with the modded CF and inky blackness with the Aikido.

Perhaps I will re-try the 5814wa at a later date.
Yes I've got 2 or 3 types of 5814 and various ECC82s but have never tried them in there, I got as far as the second ECC82 type and it was so good I just left them in! A tip on soldering pcb type valve bases if you don't already do it is to fit a valve to the socket first which then ensures the contacts are nicely aligned as otherwise they can float around a bit and may end up not contacting the pins so well.
