ReadMePA.txt Sorry, I've got a patent application in some of the principles I've used, so the PAs published will not those principles until I get some resolution on the application. One very small PA is shown in the battery amp section. This produces a couple of watts using push pull (paralleled by option) 6AK6. I've also included an all 417A/5842 power amp. This uses 15 417As to produce 10 watts. It features a push pull (parallelx5) cathode follower output stage for very low output impedance. This is described by text in all417pa.txt and schematically in all417pa.gif. A picture of the amp and PS are also shown.
