[AMPS] need info on PL-172 pentode

[Lane C. Zeitler]

This tube was used in the Hallicrafters HT-33 amp. Can't find any data on it
though in my handbooks. Looking for the filament voltage and current rating,
max plate volts and various currents and voltages of the other elements. A
web page if known where this data can be found.

Any known mods to convert the HT-33 to use another tube?? reportedly this
tube is rated at 1500 watts plate dissipation. Interesting that the company
chose a pentode.

Any info greatly appreciated.
