I have been told that the old tube output x-formers are "better" than the newer ones. Same thing with the older oil capacitors, which, I believe, contained PCB's...now banned.
I'm not sure if this is true, but hobbyists will pay BIG BUCKS for these parts...much like for NOS tubes. I have experience with NOS tubes, and I can assure you that modern tubes do not have the fidelity or the longevity of NOS tubes.
