These 6AV5GAs are pretty neat tubes! I also have lots of 6GE5s, 12GT5s, and other similar duodec and novar horixontal sweep tubes, to try out sometime, after my eyes get better. A while back I did some static testing of 6GE5s and ran them, cathode-biased with 1K and also 820 ohms, up to about 25 Watts of PD with no ill effects.
Right now, I'm seeing through a "smoky, fuzzy fog" from the "floaters" - the right eye was the first one, now the left one is starting to be effected.
What I do is go ahead and touch- type, then when I read the newly posted text , I can set up for a larger font, and then I can generally find any egregious typos and blunders
It;s a bit slow but it seems to work for now...
Fortunately there are no torn or detached retina problems, and it will get better over the next few weeks (or months, or years...), and I am under an optometrist's care for it.
It is somewhat hard to read, and watching DVDs isn't too good either , so I'm listening to a lot of radio, and tube amplified music to help pass my time.
if anything, maybe my touch typing will improve
There's a blind guy over at the Bottlehead forum, if he can build amp kits, I am sure that I can learn to deal with somewhat fuzzy eyes for a few weeks...
