Old Homebrew MRL Crystal Radio
This is a kit crystal radio that was sold as a kit by MRL (Modern
Radio Labs) which was a one man operation back 50 years ago and they
had different crystal radio kits, parts and plans that hobbyists
could build. This was their most popular set, the MRL 2 or 2-A,
which has a tapped coil, plus a galena catwhisker detector on the
front of the panel, as well as Fahenstock clips on the back to use a
diode as an option instead of using the catwhisker. This one looks
well built and I got stations loud and clear on it. Will just need
headphones and antenna and ground to get it playing for you. $77
Heathkit CR1 Crystal Radio clone
This is a clone of a Heathkit CR-1 crystal set I made
for fun but need to pass it along. It simulates the CR-1 circuit
very closely and performance is hard to tell from the original item.
I spent many hours on this one and the price hardly reflects the
effort that went into making it. You can get Heathkit performance
for about half of what you would pay for the real thing. $76
Another Prototype similar to the Heathkit using toroid coil
This is a dual tuned crystal set made in a box like the CR-1, just a
fun prototype I made a few years back. It pulls in AM stations loud
and clear. $54 (about what the parts cost)
Miller 595 Functional Clone
This is a prototype radio I built using the same circuit as the
Miller 595 crystal tuner below. It utilizes toroidal tuned coils for
high efficiency and the same dual tuned bandpass circuit as the
original Miller. Use with high impedance headphones or amp. $78
Miller Model 595 High Fidelity AM tuner crystal radio
The Miller 595 High Fidelity Tuner is actually a dual tuned circuit
crystal radio praised as the most selective crystal radio ever made.
This is made possible by the dual tuned bandpass circuit and the
vernier gear reduction tuning drive mechanism. This set is in good
working condition, and the cosmetic condition is good or better with
some minor scratches on top and fading on the faceplate. Tested and
working and I can pick up 10 or so stations here with a 15 foot
indoor wire antenna. The original output cord can plug into an
amplifier or you can hook up high impedance headphones. $125

Reproduction Crystal Detector with catwhisker and
Click photo for a larger view.
Nice reproduction of 1920's style detector on a 2"x2" solid oak
base. Features a large 5/8" diameter brass ball-and-sleeve
assembly in a tight, spring brass bracket that never comes loose,
or needs realigning. Precision ball-and-sleeve provides silky
smooth movement with no pull or backlash. Includes a selection of
loose minerals., catwhisker wire, printed instructions, and a
history of the mineral detector. $24.95 plus shipping. These are
available directly from the manufacturer, Larry Pizella, but I
don't have anymore is stock, so just click HERE
to see the order page for detectors directly from the maker.
Simple Loose Coupled Crystal Radio with Headphones #4
This is a simple little crystal set made on a nicely finished
breadboard type plaque, has a 2 circuit loose coupled circuit, with
a diode, variable capacitor with dial knob, and Fahnstock clips for
the antenna, ground and headphone connections. Complete with Cannon
Alnico 1000 ohm high impedance single sided headphones. Just hook up
antenna and ground and it picks up loads of AM stations here.
One Tube Shortwave Regenerative Radio Kit with Submini Tube.
This is a kit of parts to make a one tube regenerative shortwave
radio based on a 6418 subminiature tube. It includes all the parts
needed to make the radio as shown above, with vintage National
porcelain tuning condenser new old stock in original box, Johnson
trimmer capacitor, ferrite toroid coil core, breadboard, and all
necessary electronic components, hardware, wire, and a pair of
Newcomb high impedance headphones. There is a set of detailed
instructions, plus schematic and diagrammatic sketches to aid
construction. I have enough parts for 4 sets right now, may be some
variation in the knobs available. $49SOLD OUT
Inquire if interested and I should be able to put together
the parts for another kit but am out of the variable capacitors now,
can provide the submini 6418 tubes for $2.50 each, also have some
other submini tubes that would work.
Below is a photo of a completed set, using slightly different parts.
The frequency range as tested was 5.5-9 MHz, but the coil can be
modified to other frequencies.
