[HBR] HBR "dated?" How so?

[Peter Bertini]

Dated?

Much better tube choices became available after the design was published.
Having all of the selectivity at the second IF is also passe with the advent
of good quality, cheap xtal filters. Plug in coils are a pain, but probably
a worthwhile tradeoff for Q. Toriods would do a better job for the RF stages
in a modern design.
