[Hallicrafters] Replacement Capacitors

[Philip Atchley]

Hi.
I think that if the original circuit was rated at 10 uF 1200 Volts then I
would, AS A MINIMUM use three 33 uF 450 VDC capacitors in series for a value
of 11uF at 1350 VDC.  GOOD repair/overhaul practice dictates that all
replacement capacitors MUST at least equal the originals in value and
exceeding those values a little doesn't hurt, especially in today's world
where the line Voltage is HIGHER than the gear was designed for!
