Yup tubes & PCB's do not mix. All those parts out in the air, PWR
resistors strapped to the steel chassis. Solder pots that dont go cold
( only the grounds ). And I loved that hookup wire. Braided & tinned
a rubber insulation all wrapped in a fine cloth in any color.
Pretty amazing they could do it & compete with RCA, a much cheaper
set to build.
