It' not necessarily just the wooden cabinet, but the general internal
acoustical design of the speaker system in the radio...etc. Back in
the day, (I assume that Counsellor Ross' radio is of 1950s to mid
1960s vintage). - this was way before most consumer electronics were
made by $2/hr labor in China - the manufacturers paid more attention
to sound quality, tuner performance...etc.

I have heard that the reason that the $2,400 per meter speaker cable
crowd likes vacuum tubes, is because the type of harmonic distortion,
that a tubed amplifier generates is pleasing to the ear, and is
perceived as a warmer, 'richer' sound, if you will.
