Heathkit DX-35. Crystal-controlled phone & CW transmitter. 6146 final amplifier providing 65 watt plate power input on CW, with controlled-carrier modulation peaks up to 50 watts on phone. Built in modulator and power supplies, covers 80, 40, 20, 15, 11, and 10 meters with a single band-change switch. Pi network output. Tubes: 12BY7 oscillator, 12BY7 buffer and 6146 final. Speech amplifier 12AX7, 12AU7 is used as modulater. Panel control: switch selection of three different crystals (reached through access door at rear). Panel meter indicate final grid current or final plate current.
Heathkit DX-40. DX-40 is a 6 band AM and CW transmitter manufactured between 1958 + 1960 at an original cost of $64.95 by the Heath Company, Benton Harbor Michigan. The DX-40 runs on 75 watts CW and 60 watts AM. Front panel features include a large meter calibrated to indicate both grid drive and plate current, grid and plate meter switch,on/off/tune stby/AM/CW switch, final and antenna tuning controls, drive level control, 80/40/20/15, 11 and 10 meter switch, power on lamp, microphone and key jacks and utilizes a 6146 final output tube. It measures 13'' W 9'' D 81/2'' H and weighs 25 lbs. Supplementary photos. Credit to Nels Huuskonen for allowing his photos shown here.
Heathkit DX-60 phone & CW transmitter. The DX-60 (according to Heathkit) "was designed as a versatile and economical transmitter for General and Novice class amateur operation. It features up to 90 watts input, controlled carrier phone operation, four switched crystal positions, and provisions for the use of a VFO. Panel controls allow for CRYSTAL or VFO, and PHONE or CW Operation. Front panel controls consist of the BAND switch, DRIVE TUNE control, DRIVE LEVEL control, CRYSTAL-VFO switch, FINAL TUNING control, FINAL LOADING control, and Function switch. The illuminated meter face is calibrated to indicate both grid drive and plate current. A slide switch, directly below the meter, enables the operator to rapidly check grid drive or plate current. The MIKE and KEY jacks are on the front panel for easy accessibility. An accessory power socket is provided on the rear chassis apron. At this socket, 300 volts at 50 ma DC and 6.3 volts AC are available for VFO operation. Switched 117 volt AC power is also available for antenna relay operation. " The DX-60 uses 5 vacuum tubes with a 6146 in the Final Amplifier. Supplementary photos. Credit to Nels Huuskonen for allowing his photos shown here.
Heathkit DX-100 HF Transmitter, is the Heath answer to the Johnson Valiant. It operates 160 through 10 meter Ham Bands in AM and CW. It has an internal VFO, essentially a FV1 inside the case. It uses a pair of 6146 Final tubes plate modulated by a pair of 807 tubes.

Heathkit HG-10 external VFO. Manufactured between 1961 and 1966 the HG-10 is designed as matching accessory for the DX-60, 60A, 60B and the HW-16 line of transmitters. The HG-10 is calibrated to cover 80-10 meters but will provide drive on 220 Mhz and 440 Mhz as well. Features include: on/off/spot/operate, frequency and band controls. Rear panel connections include an rca phono and rf output jacks, 1/4'' key jack and power cable. It weighs 12lbs and measures 9.5''W+6.5''H+9.25''D. Supplementary photos.

Heathkit Two meter transceiver (lunchbox).
Heathkit TWO-er. Crystal-controlled transmitter with tunable superregenerative receiver with RF stages which is Ideal for emergency communications. Thousands of these transceivers now in use across the nation, in homes, offices, cars, trucks, boats, etc., attest to their popularity and proven performance. Their neat, compact design, low cost and high versatility make them ideal for use in either mobile or fixed station installations. All feature crystal-controlled transmitters and tunable superregenerative receivers with RF preamplifiers designed for operation on the 2, 6, or 10 meter amateur bands. The highly sensitive receivers pull in signals as low as 1 microvolt and produce complete quieting on reasonable signal levels.
The transmitters with up to 5-watt input are more than adequate for "local" net operations and the
communication range of all models is unlimited under "skip" conditions. Other features include: a built-in
RF trap on the 10 meter version to minimize TVI; frequency multipliers on the 6 & 2 meter versions to
provide straight-through finals from an oscillator using a fundamental crystal in the 8 mc range; built-in
final amplifier metering jack, and "press-to-talk" transmit/receive switch on the front panel with "transmit-hold" position.
