SSR-III Hot Rod



These are nice meter
movements available at
several sources (Mouser,
All Elect, MPJA).They are
relatively inexpensive as
meters go. I have used
them on other projects
and they are very reliable.
These are 1 mA meters,
calibrated for 15 VDC,
but you can remove the
15 k Ohm resistor (blue
item to the right of the
movement) and
recalibrate them as you
like. (More on that later in
the project as I calibrate
them to the individual
circuits.)
Here are the meters
being disassembled, one
with its cover already
snapped off the case.
NOTE: The log book in
the photo is available
here. It's indispensable
for an AM BCB DXer.)
This is a scan of the
meter artwork. Each
meter face is printed on
peel 'n' stick label stock.
They are 2" wide by 1"
high, each.
The labels are printed on
a decent color printer,
cut to size, and applied to
the meter face with
tweezers and a steady
hand, by sliding the label
behind the pointer. I
usually apply a thin coat
of clear acrylic to reduce
ink fade (spray lightly
and dry).
This is a photo of the
finished meters. Once
the ink is sealed with
clear Krylon, and the
resistor removed, the
meter faces will be
reattached with a drop of
anaerobic glue - one
drop each side, only -
that's enough to hold it
securely, yet you can still
remove it with a #11
Xacto blade for repairs,
mods, etc.

The panel with the meters installed. You can refer to
the panel layout photos at left. Note, due to the size of
the controls behind the panel, I had to move the
toggles inboard. This also gives a little more finger
room for spinning the knobs.
