Ah, nice Tony. 

I built one of those in 1954 and later added that grid block keyer (on the
elevated chassis just visible above the VFO "can"). Ran it for the next 20+
years, pounding brass 99% of the time. 

The metal tubes are really 1614's - 6L6's on "steroids" that were developed
for the military during WWII. Like many of the kits available in the 1950's,
E.F. Johnson relied heavily on the huge quantities of WWII "surplus" parts
available. 

The Ranger is an outstanding little rig. Had the pleasure of rebuilding one
for a buddy just a couple of years ago. 

One of those would make a great bootleg AM transmitter, with its plate
modulation with negative feedback in the speech amp for outstanding
linearity.

Speaking of 50W on AM, this picture will make your mouth water if you're old
enough:

<http://home.comcast.net/~bipi/pix/ranger1.jpg>Note the little details: the
parasitic chokes, the 6L6s in their iron cylinders, the output pi-net, the
plate choke.....if you want to put a bootleg AM station on the air from the
jungle, that's what you need, right there in that pic. That, plus one of
those old 1-ounce xtals in the FT-243 holder.
