[Johnson] Will be restoring a Johnson Ranger

[whitebear1122 at comcast.net]

I once had a talk with John Magnusson who designed that grid block keying
modification for the Ranger.  He said that Ranger designer Manley Youngberg
had already left the company and he (John) was finishing the manual and
resolving production issues, and this keying issue.  So he was the Johnson
engineer who designed it and carved it into the Ranger circuitry.

About 30 years ago I acquired by a roundabout way a first version Ranger
that had the keyer kit installed.
To avoid a looong discussion of how I got involved with that ckt....I can
say that the way to determine if the keyer kit was added is to look at T3.
The original first version of the Ranger does not have a T3 secondary tap
from the keyer bias.
The next version schematic dated 11-5-54 shows the keyer and T3 tap.
I've never been able to find any installation info from the kit for the
keyer.
I still have this Ranger and plan to service it again soon.....for the 3rd
time!
There were 3 published schematics for the Maroon colored transmitter, the
original had no date, next was 11-5-54, then 10-17-57.
Great transmitter.
The Ranger ll that had 6m is a different transmitter.
