[Heathkit] SB-200 @ 50 Hz

[manualman at juno.com]

Interesting, on page 4 of the SB-201 manual under Introduction, it says
50/60 Hz, yet on page 44, under Power Source, it just says 60 Hz.

Personally, I don't see where 50 or 60 hertz would make that big of a
difference relative to the power transformer. The fan motors in both
amplifiers also use the same part number AC fan.
