breadboard kit. Includes 40 meter crystal. (Based on Article in May
2006 CQ Mag.)
Transmitter Kits and Accessories Page
|This kit is based on an article in May 2006 CQ Magazine entitled
"Look Ma - No High Voltage" It is a milliwatt range vacuum oscillator
kit assembled breadboard style using a new old stock vacuum tube
that uses 12 volts dc on both the filaments and the plate. Great safe
way to learn about vacuum tube operation. Also included is a 16 page
manual written by the author, a pre-wound 40 meter coil, a spare
plastic coil form and a new 7 mHz crystal which can be soldered
across the crystal socket provided in the kit. The power output,
unfortunately, will probably not be useful for ham communications
outside of the shack. This kit is still a great way to learn some of the
basics of a vacuum tube crystal controlled circuit. Perfect for code
practice across the ham shack to your 40 meter receiver. The
assembly manual is similar to (maybe better than?) the manuals that
came with the radio kits in the 1960's. Plenty of illustrations and step
by step instructions.
One of the first products from Pastime Projects.
$28.00 plus $4.00 shipping. Limited quantity.
|This is a carefully planned and designed replica of a
late 1940's design code (CW) 'home brew' transmitter. This kit
includes Amish prepared oak slats and end blocks. You assemble
with supplied instructions and brass plated flat head screws. The
kit includes terminal strips, solder lugs, tube sockets, wire, newly
manufactured variable capacitor, resistors and tested NOS or
import 6V6 or 6L6 vacuum tube, and a very detailed step by step
manual. Will operate on 80 or 40 meters by changing the hand
wound coils. Uses FT 243 type crystals. 2 to 10 watts out
depending on the power supply.

PPS-1Power Supply Kit $ 109.00
|The PPS--1 power supply includes sold oak slats and
end pieces that form the "chassis" with brass plated flat
screws for that vintage look. 120 VAC primary voltage.
Output as supplied approximately 200 VDC max.
Transformer rated at 250 VCT @ 130 ma and 6.3 VAC @

instructions. Features fused input, transformer
isolation, filter choke and filter capacitors, a bleeder
resistor, indicator lamps in the filament and hv circuits,
Use the power supply kit for your favorite tube type
transmitter or receiver. This kit requires assembly,
soldering, and testing and builder familiarity and

|This kit has been written up in QST magazine, and is subject of many posts on popular web sites.
The design originated in the late 1940's and was published by the ARRL (American Radio Relay
League) in many magazines and handbooks. It was originally a "do it yourself" design with very
little instructions. It used "Orange Crate" wood for the chassis, brass screws, sucker sticks for
holding the coil in place, and a coil that is wound around 8 penny nails laid out in a circle.
Our design includes Amish prepared oak strips and end pieces, brass screws, "sucker sticks",
and the nails to construct your coils just like the original. Many of the components are new (and
we think more reliable than originals) but the retro look remains. This kit will operate on 80 meter
or 40 meter CW ham radio frequencies with power out in the 2 to 5 watt (or more) range. It is
crystal controlled. Change from one band to the other requires different coils be soldered in. The
40 meter version seems most popular amoung our builders.. The manual that comes with this kit
contains step by step instructions for assembly, wiring, and soldering. The included vacuum tube
will be a new import which has been retested here and certified. The builder will need a crystal
and power supply.
To put this kit on the air a license, antenna, and power supply will be required. The builder
should be familiar with working around high voltage before applying power to this kit.
A paper on high voltage dangers and safety practices is included with each kit.The radio is
shipped in a sturdy commercial box and the packaging has been tested over many years to
assure safe delivery..
