[Johnson] Need Viking Ranger EXPERT

[Bill Cromwell]

Hi John,

Other advice was good. I just gave you a place to start. As you now know,
your Ranger has electronic keyer already so no bother about the first
version of the wiring. Those diodes are most likely a conversin to solid
state from the original vacuum tube diodes 6AL5 that were mentioned in
another post.

73,
