| 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. |

| 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 and mellow, and illustrates the magic of vacuum tube amplification. Output level is controlled by the input device. You provide common interconnecting cables and 8 ohm speaker and 12 volt power supply. With tubes tested and warranted. . PRICE $37.00 |
My ten year old grandson put one of these together recently. 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. $10.00 DELIVERED TO US |

| "Remember When" 6V6 Transmitter Kit |
| This is a carefully planned and designed replica of a vintage code (CW) 'home brew' transmitter. This kit includes slats and end blocks of solid oak wood prepared by Amish craftsmen to our specifications. Brass plated screws are provided as well as terminal strips, solder lugs, tube sockets, wire for coils and hookup capacitors resistors and much more. The manual is very detailed and well illustrated. This kit is supplied with a tested 6V6 tube and is capable of operation on both 80 and 40 meters with a coil change and the proper selection of a crystal (not included) . Power output will typically range from 2 to 12 or more watts depending on tube and voltage available. PRICE $59.50 IN STOCK READY TO SHIP |

| "PPS-1 Alham" Companion Power Supply |
| The PPS--1 Alham power supply kit was introduced in February 2008 as a companion for the 6V6 "Remember When" Transmitter kit also offered by Pastime Projects. The Power supply is supplied with sold oak slats and end pieces that form the "chassis". These are held with brass plated flat screws for that vintage look. The power supply uses 120 VAC primary voltage and provides DC output and filament output through a transformer rated at 250 VCT @ 130 ma and 6.3 VAC @ 2A. Features include a manual of 19 pages that contains illustrated step by step instructions. The power supply features fused input, transformer isolation, a filter choke and filter capacitors. A rugged bleeder resistor is included. The input and filament circuits have an indicator lamp. The high voltage circuit has a neon lamp which indicates the presence of high voltage. The potential for uses of the power supply are many. It may easily supply voltage for a tube type receiver. This kit requires skill in assembling the wood chassis as well as assembly of parts, soldering, and testing. Recommended for those with experience working with high voltage circuits . $109.00 |
| We have just finished the initial run of our 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.
