Did the same thing!! Even used the chasis! Sawed it off, moved the front
cover/ cap, and rotary inductor into the area of the osc/ magic eye tuneing
tube area-- makes nice package, and considering these tuned from around 160
meters thru 20 (or thereabouts) in different versions, and loaded a aprox 20
foot piece of wire--- make very versatile tuners . also wonder where all
of the bazillions of these dissapeared to! Jim

Dick, A REAL LONG time ago when I needed my first tuner I bought a
military surplus ARC-5 transmitter for $5 USD and removed the roller
inductor and final plate tuning capacitor. [Actually, I bought 3 ARC-5s:
one for 80, one for 40 both converted to XTAL control, and one for the
tuner and spare 1625s. Nice NOVICE CW rigs.]

Made a real nice L-tuner at 125 watts continuous duty!!

Hmmm .... where are those old ARC-5s when someone needs them??

In a time long, long ago, there were no commercial antenna tuners that
I can recall. The first commercial tuner I remember was the Johnson
Viking. Everyone I knew made their own. You just went to the surplus
store, and got a coil and capacitor that looked about right, and tried
it. No one owned any equipment to measure them anyway. We never used
relays. Maybe a switch, or just change the coil. The ARRL handbook
and Antenna Handbooks still have diagrams for antenna tuners. Also
the Hints and Kinks manuals, among many others.

Mark,
What sort of range of impedance matching would this provide?
How would you switch bands and what voltage/capacitor range
would be required?
I suspect you would have to have several relays to pick up various
points on the oatmeal inductor as well as a rotation method
for the capacitor

Seems like you have something specific in mind that you would put in a
box
for safety reasons. Are the specifics shown somewhere for people to
copy?
