Morris, If your KPA100 works FB, do not change anything.
I have it on good authority that the real problem is not the capacitors, but the resistors, particularly the 1.6 ohm 2 watt resistors. Apparently the manufacturer changed to an inductive design without consulting with their clients (including ELecraft). As a result, you can look for Builder's alert 22 to be resinded and replaced with a new one. Again, if your KPA100 has good output on all bands, this is NOT for you - it only happens to those unlucky folks who received resistors that are inductive with their kit - the older resistors are non-inductive, and no change is recommended - 'If it ain't broke, don't fix it'. 73, Don W3FPR > -----Original Message----- > > I have one of the older KPA100s and have done all the mods and > upgrades.
