Greetings -
I recently made some minor
modifications to my Drake MN-7 antenna tuner and now find myself backed
myself into a corner. Maybe someone has a suggestion.
I like the MN-7 and MN-2700
tuners but I really wanted some way to illuminate the meter with a couple small
12 volt dc lamps. So I installed a couple lamps over the meter, drilled a
small hole in the back panel, and inserted a standard phono jack for running 12
volts dc into the unit. I also drilled a small hole in the front panel
(just to the right of the meter); my intent had been to install a mini-spst
toggle switch there for controlling the 12 volts dc to
the lamps.
Sounded like a good plan to me -
I tested the system to make sure I would get illumination; "measured twice and
drilled once"; etc etc etc. All went well until I tried to install the
mini-spst switch (which I bought at Radio Shack) in the hole I had just drilled
in the front panel. Doggoned if there isn't a double panel on the front - the
metal enclosure plus another "plate" which I guess is bakelite. In any case, the
threaded cylinder portion of the spst switch (onto which the nut fastens the
switch to the panel) does not extend far enough out the front of the panel
for me to get the nut on it.
Bummer. Now I have a nice
centered 1/4 inch hole in the front panel of my tuner.
The threaded portion of the spst
switch that is designed to extend through the panel is 5/16 inches
long.
ANYBODY KNOW WHERE I CAN FIND A
MINI-spst TOGGLE SWITCH WITH AT LEAST 3/8 INCH THREADS ON THE BUSHING THAT
EXTENDS THROUGH FRONT PANEL? I don't need much more length; right now when
I shoulder the switch against the front panel, the end of the threaded cylinder
is flush with the panel.
I went back to Radio Shack but
they said they do not make these mini-switches with longer shanks. (Where
is Allied Radio and/or Newark Radio when you need them?)
Any suggestions are welcomed -
thanks
