Helo fellow AM enthusiasts,
I just picked up a old Johnson Ranger II.
Looks completely original, as far as I can tell.
Even all the caps look original! Hard to believe.

So,
1) The VFO bezel has a 1/8" dia paint spot missing and I would like to 
either get a different one, have this painted, or fix it my self....any 
suggestions?
The front panel is excellent except for this one area.

2) Brought it up over 8 hours on a Variac and nothing bad happened 
(even though I did hear 1 little arc). It is now at 115VAC. I do plan 
to put a 3 wire cord on it and fuse.

3) Followed the steps in the book to tune up...20 watts out on 80, and 
12 out on 40??
a) plate voltage is around 600. Grid drive set at 2 ma.
b) dummy load
c) key down

4) When I checked modulation current it went all the way over to the 
right... I see a step to adj. that in the book, but wander why it is so 
far off?
plan on getting a new R39 as this one looks kind of beaten up.

5) I find the manual a little lacking..what is the plate voltage right 
on the plate cap supposed to be?

6) I plan to get a cap kit and replace all caps soon.

7) This has not PTT mod in it. Which one is the best? (Johnson manual 
one or others I have seen on-line)

8) is a matching paint formula available for the front panel and 
cabinet?

Excited to get this going and work some of you on AM!

Thanks,
73,
Lee
