40 Watts, 87% Efficient, No Heat, All On A 2½” Board!
The UAM4 is the big brother to the extremely popular UAM2. It uses the latest
spread spectrum amplifier technology to bring you clear, crisp, high-power audio
without any of the heat which is normally associated with such an amplifier. It’s
extremely clean Class D design produces two independent 20 watt outputs! This
can also be bridged to an extremely efficient (87%!) single channel (mono) 40
And at 40 watts, you’re probably already wondering about the heatsink requirements to dissapate the heat, right? Stop wondering, there’s no heat, so there is
no heatsink required! And all that power is generated in a single SMT device the
size of your thumbnail on a small 2½” square board!
The high impedance input is designed to use your choice of either a balanced line
input or an unbalanced signal source using easy to connect Euro terminal blocks.
Logic connections to ground are also provided to mute and/or shut down the
amplifier. You can also enable the built-in over temperature signal to activate one
of these controls automatically! Easy to use board jumpers offer selectable gain of
+22dB, +25dB, + 29.5dB or +36dB to match your input levels. Board jumpers
also enable protection and shutdown options as well as stereo/mono/bridge
mode. The amplifier also features built-in click and pop suppression to protect
not only your ears and sanity, but your speakers and equipment!
Power input for maximum rated output is 18VDC at 2.64A. Input voltage can be
reduced to a minimum of 10VDC while maintaining the same high efficiency
operation with reduced output power. If you’re looking for an incredible stand-alone stereo (or mono) amplifier to build into your equipment, vehicle, speakers,
or application, the UAM4 is the latest and the greatest!

The Nixie tube made it’s debut in 1954 and became the standard in high-end
test and military equipment. We brought it back in 2008 in one of the neatest
digital clocks available today!
It features six IN14 Nixie tubes mounted in a beautiful hand crafted and hand
rubbed Teak and Maple base. Advanced features include 12/24 hour format,
brightness control, soft fade out, and auto-dim for selected windows of time.
Runs on 12VDC with included AC power supply and utilizes a crystal time base
accurate to 20ppm. You will be mesmerized watching the bright orange glow!
Available in kit form or factory assembled. See this beautiful clock and other
models in action at www.ramseykits.com/nixie. You’ll be amazed!

Passive Aircraft Airband Receiver
✔ Monitors the entire 118-136 MHz aircraft
band without tuning!
✔ Great for air shows!
✔ Passive design, can be used onboard aircraft!
✔ Patented circuit and design!
For decades we have been known for our novel and creative
product designs. Well, check this one out! An aircraft receiver
that receives all nearby traffic without any tuning. It gets better...
there is no local oscillator so it doesn't produce, and can't produce, any interference associated with all other receivers with an
LO. That means you can use it onboard aircraft as a passive
device! And what will you hear? The closest and strongest traffic,
mainly, the one you're sitting in! How unique is this? We have a patent on it,
and that says it all!
This broadband radio monitors transmissions over the entire aircraft band of
118-136 MHz. The way it works is simple. Strongest man wins! The strongest
signal within the pass band of the radio will be heard. Receiver sensitivity is less
than 2uV for detectable audio. Headset cord is coupled as the antenna giving
you great reception. Also includes a set of stereo ear buds. Runs on a standard
9V battery. Available thru-hole kit or SMT factory assembled & tested.
