If one were to construct a demand curve (or surface) with three axes – predicting units sold as a function of price and RF power – I would bet there would be a significant discontinuity at about 600 – 700 watts. Below that, an amp can run from ordinary home 117 VAC without a dedicated line, as I now run my KPA500. Above that it begins to become dicey to do so; and at some point below 1.5 KW it requires 220 VAC to the desktop. That means that even if the selling price of the amp were smoothly continuous with the power output, the total cost to many buyers would not be. It would require some buyers’ investing in additional wiring to the shack, as mine would. So I would expect the demand curve to have a so-called downward knee somewhere above 500 watts but lower than 1.5 KW, which could change the production investment analysis significantly. Among other factors, that might have helped make the KPA500 a financially optimal choice.

I believe they built a couple of prototypes to evaluate the feasibility of making such a product. In the end, it was decided that it would not be an economically viable addition to the product lineup and was shelved. No conspiracy. Nothing sinister. But sadly for those who might want to buy such a beast, nothing in sight along those lines. - Brendon KK6AYI ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
