As far as hand wiring goes you should never mix PCB's with tubes.
Look at the hook up wire. Most is braided & tinned with rubber
insulation then covered with cloth. The cloth had tasteful colors & tracers
in lots of shades & were color coded to the set. Example white / blue
is AFT. Yellow is video, etc. They must of spent millions over the yrs
on that wire. Premium parts were common such as the use of Bel fuses
& Sprague caps.
Enuf fer now

I have to disagree with the part about tubes & PC boards. My Mag T940 Astro combo from early 1970 is a PC board based tube chassis and despite the use (and abuse) of us growing up it has never had a heat related PC board issue be it bad solder or tube sockets going weak. The only real service has been the numerous 6GH8's and 6JE6's replacements along with a sagging heater in the 3A3 that was caught in time. The set survives to this day with plenty of life in the old jug.
There were plenty of bad designs with point-to-point and PC boards, the Zenith YC had its share of problems as well that were heat related.
