Thanks Frank, I wouldn't ask you to do all that work, but I haven't been able to find a good history in English about the illustrious EL34.

You don't have to.

Just go to one of these sites, paste in the link for the website you want to translate, select the translation languages, click, and your life is jelly!

Best,

Hi,

While Worldlingo seems to be on strike tonight I thought I'd give Googles' service a go.

I must say I'm impressed. This is by far the best translation I've seen.

If I find the time I may just as well touvh up the lot, turn it into pdf format and archive it on CD-R for future reference.

Thanks, George

You are all very welcome.

Consider it my first reciprocation of all the generosity
you have shown me in my incessant questions.

Best,

Hi Frank,

Thanks for the history lesson! The tree at the top of the page explains it all. Phillips invented the pentode, RCA as a counter the Beam tetrode beacause of the kink that all tetrodes produce when the plate voltage falls below the screen (G2) voltage. IIRC the so called kinkless tetrodes. That's also why Phillips invented the power pentode because of that kink. That's how the U.S. version 6CA7 got around the patent issues.
There's an article in one of my Audio Express mags. that covers this. I'll have to dig it up.

Wayne
