Product Description

This Heathkit TX-1 " Apache "  Transmitter, is in Very Good Condition.

It has been stored used, for many years.

It should have the electrolytic capacitors changed before putting it into service.

I am selling it as is as described for the family of a silent key.

 

It is very heavy and I prefer a pick up but if I do ship, it will be at the risk of the buyer.

I am an expert packing heavy vintage gear but there is always a risk.

The shipping estimate is just that, an estimate. I will only charge the actual amount it cost me to ship to your address.

    Famous for value ... "Apache" AMATEUR TRANSMITTER

    Representing the entire transmitting complement of the amateur station, the "Apache" incorporates many fine features and modern styling to bring you all the extras required for effective and dependable communications.

    The "Apache" operates with 150 watt phone input and 180 watt CW input on 80 through 10 meters and features chassis provision for plug-in connection of the Heathkit SB-10 SSB adapter. A specially-designed VFO provides minimum drift frequency control necessary for SSB transmission. The illuminated, rotating slide-rule VFO dial with full gear drive vernier tuning provides ample bandspread for accurate frequency settings. Each amateur band is separately calibrated on the rotating slide-rule dial for maximum accuracy. Also featured in the "Apache" is adjustable low-level speech clipping and a low distortion modulator stage employing two 6CA7/EL34 tubes in push-pull class AB operation. Time sequence keying is provided for "chirpless" break-in CW operation. A "spotting" push button allows tuning of the transmitter before switching on the final amplifier and also enables the operator to "zero beat" an incoming signal without placing the transmitter on-the-air. The final amplifier is extensively shielded for maximum TVI protection and is neutralized for high stability. Pi network output coupling provides smooth loading into antenna impedances of 50 to 72 ohms.

  • The Apache's modern styling, identical to the Heathkit Mohawk receiver RX-1, presents a smart appearance that any amateur would be proud to display in his station. Color styling is in the traditional Heathkit amateur radio colors of gray and gray-green. Front panel control knobs and escutcheons are of heavy die-cast metal which impart a rugged, handsome quality to its overall appearance. The precision mechanical controls operate smoothly with the positive action characteristic normally found only in the most expensive equipment. The formed one-piece cabinet has a convenient top hatch for easy access to tubes and crystal socket.
