Re: e-mail from Thomas Mayer about EC8020

192.135.193.34

From what I see of the plate suport in the picture and the tube I'm using are the same. The envelope on the National labled EC8020 is about twice the hight and maybe a little bigger in dia then the 5842. The plate size is about twice the size as well. I called Richardson and they are checking their stock. I'll report back as soon as I know. Again I don't think the EC8010 could drive the 572-10 into class A2 as it has twice the plate resistance. I've been running the National tube for several months without any plate spots. I would also think the EC8010 would start spotting run a almost twice its rating. Does anyone have a picture of the EC8010? Or better yet the EC8020 and EC8010 together?
