[Elecraft] Alternative Amplifiers for HF

[Edward R. Cole]

I will not advertise very often on this list, but I do want to remind 
folks that I am developing a couple HF amplifiers that will work with 
either the K3/10 or KX3.  One takes 5w drive to provide 140w output 
(12vdc), and the other takes 12w drive to provide 275w (28vdc).  Both 
are assembled versions of the kits offered by CCI with addition of 
chassis, connectors, LP filters, TR relays in a complete package vs 
the plain pcb amp parts kit that CCI offers.  Essentially, I am 
offering a kit building service + packaging.

Its taking me a bit longer to work out some details like the custom 
pcb for the six-band LP filter and some delays in suppliers for my 
300w prototype (I am building for myself).  On air reports have been 
good, so far, but full testing remains after the LP filter 
installation.  This should not be confused as a "KPA250" (smile): A 
more basic amplifier for a little less money (take the link at the 
bottom line in my signature).  Hoping to have start date in mid-April.
