Thanks for the reply Don, much appreciated. Just to clarify, I built up the amp last year but never got around to installing it. So around December 06 I obtained the upgrade kit and installed that as well and that's how things stand at the moment.
However your reply and mention of the new C31 had me looking around the Elecraft site and I see that there is an errata dated 4 December 06 which stresses the importance of changing R19 & R20 even though the correct values may already be installed - needless to say when I did the upgrade I followed the original instructions which basically says (on page 4) if the correct value components are already installed go to the next section. So, the upshot is, that I need to strip down the amp, replace R19 & 20 with the low inductance type, check the other components in accordance with the latest errata and install a new C31. At which point I should be in a position to check out the amp properly. 73 to all Trevor G0KTN _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
