The last "Amp" key went to its new home on December 18th, 2006.  This

page is left in place for historical and reference purposes.    


The Amplidan model 50713 telegraph key is one of the classics. Used by ships' radio officers all over the world, the Amplidan key has a reputation like no other. Professional quality from stem to stern. They're also scarce-- Amplidan stopped making the keys 10 years ago and Morse Express has acquired all remaining keys from the factory.  Amplidan keys were sold as part of marine communication systems, and as a component for other OEM's systems. Although the keys are no longer in production, repair parts are still available from Amplidan.

These keys are brand new, in original factory packaging.  The attached cable has a 6-pin DIN connector and the cable itself would be easy to replace.  There are felt pads on the bottom, with the Amplidan label as shown:


The key weighs 2.3 Lbs (1.1Kg) and the base measures 8-7/8" x 2-3/8" with overall height 2.25" to the top of the knob. Two large thumb screws provide for quick and precise adjustment of contact spacing and lever tension. 

The base is a steel plate and with that LONG lever this is one of the most stable keys around-- an absolute joy to use. Your fist will fall in love with it instantly, or we'll happily buy it back from you!

This is the key that a retired radio officer recommended
as the finest straight key available in the world. How
could I resist??  Of all the straight keys I've tried the
Amplidan is certainly the very best.

The Amp is an imposing presence on the desktop. There is no
question it was designed to be used in a commercial setting
as everything about this key is heavy duty. Yet it is simple
to adjust, even for those who prefer a "fine" thread on the
tension and gap settings. The key occupies 9.25 inches by 2
3/8 inches by 2.5 inches of desktop real estate. The knob
resembles a baby's pacifier with a skirt that is smaller
than the conventional "navy" knob. It's a different but not
unpleasant feel. The truth is, sending with this key is as
effortless as straight key sending can be. I'm delighted to
have the Amplidan as part of my CW sending collection.
