[Elecraft] Alternative AMP to KX3 since Elecraft has temporarily stopped making AMPS

[Hank]

I'll second the Hardrock 50w.  Not only does it work really well (including its tuner), it was a ton of fun to build.  It integrates well with the KX3 for band changes, PTT, etc.

I realize you are looking for a 100w amp but if you like building kits, the 50w Hardrock is a very fun project and works well.

I built one and have used it on SOTA activations when I want something more that 10-15w.

I also have two KXPA100 that I use often and also enjoy.

Very reliable and fun to use when needed. But I typically use the amp with my IC 7300 during RTTY contests when needed. You will need an interface like the Ameritron ARB-704 for the keying of the amp.Good luck and 72/73,de KI8I DaveSent via the Samsung Galaxy S10+, an AT&T 5G Evolution capable smartphone

>   stopped making AMPS I have a KX3 and looking for an AMP (besides the elecraft brand) that is 100watts or more that will work flawlessly with it.I ordered the 100 amp from elecraft, but have been waiting over two monthsfor it, but they are out of stock and will be for some time. Has anyone purchased something else and has used it for a while with reallygood results?  If you have not tested or used an alternative AMP for theKX3, please don't respond to the post.  Just looking for those who haveactual results instead of suggestions.  Greatly appreciated.
