[Heathkit] Mohawk Mods

[Larry Knapp]

Tony - There are actually four ER articles referencing Mohawk
modifications...the fourth is May 99 ER offering a full schematic and one more
mod to the audio...unfortunately, according to some eMail I exchanged with the
author many months ago, these full schematics are no longer available.  These
are excellent articles....have not done any of these mods yet, but technically
unchallenged.
