[Hallicrafters] HT-33A amp followed me home

[Fern Rivard]

    A Hallicrafters HT-33A hf amplifier with the Penta PL-172A final
followed me home in the past few days. Does anyone have any mods that
were pertinent to those amps that I should be made aware of? Also what
is the approximate value of such an amplifier? It is in pretty good
cosmetic condition except for a broken glass on the front of the
multimeter. Any useful info on replacing that glass would be most
helpfull.
    Thanks and 73 from Fern
