| Based on our article in the May 2006 CQ Magazine entitled "Look Ma, No High Voltage" this design uses a vacuum tube from the 1960's that operates on 12 volts on both the plate and the filaments. The tube is included in our kit. Construction is very simple using the 16 page assembly manual. A 40 meter prewound coil is furnished, along with another coil form to allow the buyer to experiment with other frequencies. A crystal holder (HC-67) is provided. Since crystals for this type socket are not easily found, a new solder in qrp crystal on 7.04 or 7.03 is now provided in the kit. Output of the prototype oscillator was in the 40 to 60 MW range. The author wrote a newsletter article describing a 12K5 amplifier that brought the power up to 400 plus MW. The article is included in the manual $30.00 (LIMITED SUPPLY) |

| Qrp CW TX Low Voltage Tube Kit as seen in CQ Magazine - The "look Ma" Kit |
| This Ohio USA Manufactured Kit includes an oak "chassis", two tubes, and all parts and wiring needed to assemble this kit. Very well illustrated manual. Supply any 12 volt DC at 1 ampere or more power supply, then connect your favorite crystal set, regenerative receiver, Walkman, or any headphone device in and hear the output through a low impedance (4 or 8 ohm) speaker .The sound output is soft (quiet room level) mellow, and illustrates the magic of vacuum tube amplification. The amplifier now includes a volume control and knob with hook up instructions. All resistors are now color identified for your building convenience. You provide common interconnecting cables and 8 ohm speaker and 12 volt power supply. With tubes tested and warranted. . PRICE $42.00 |
Features that make assembly easy include an oak 'saddle' already glued in place on the oak base. The necessary holes for the dowels are drilled. The wire connectors are already soldered to the copper contact boards. The lugs are fasted to the other end of the connecting wires. The pilot holes for the terminal screws are drilled. This is a simple project that results in a useful key for beginners as a first key to encourage Morse code understanding. $ 7.00 August Sale EMAIL TO BUY WITH PERSONAL CHECK |

| New straight key for cw (code) transmitting. We have named this key the "Click-Key II". It uses a micro switch for the contacts. Micro switch contact life runs anywhere from 100,000 to 1,000,000 closures. Thats a lot of cw! The use of micro switches is not new to cw keys, but some of the other features of this switch make it worthwhile to the beginner or to the expert/collector. Might make a great presentation gift for your club. Includes a solid oak base, oak saddle for the switch housing, and a clever mix of household items that truly make this a conversation piece. Use it next SKN. This is a kit, and will go together easily. There is a couple solder joints, some screws and spacers to install and adjust, and, of course the knob assembly itself. $ 10.00 |
