• WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
    Building, troubleshooting and testing of these amplifiers should only be
    performed by someone who is thoroughly familiar with
    the safety precautions around high voltages.

Mesh plate tubes

The plus-side to threads that build a momentum, and move on to nearby matters - they keep rolling and tempt folk to think and add to a hot discussion. And widening the talk to other tubes of the era of original Mesh Anode designs is not so far off topic anyway.

Atomizing a debate into slow moving fragments can kill the enthusiasm, and good contributors drop out.

Anyone searching rare valve types will find that specific information -> no problem!

Just as importantly, Andy @andyjevans is the OP. His choice should carry most weight.
 
It's broke Andy. It is like a parts box with the wrong label. The contents may as well be discarded as you can't find them. Is this what you want? Or, should the original topic be renamed and discard the other excellent information?
Oh, for heaven's sake, there's a "search" function on DIY Audio. Why don't you stop manipulating everyone here as if you're the only person who knows the truth of everything in life? Sheesh......

Why do you need to "clean" the thread? Who has asked you to do that? Could you be transparent please? Thank you.
Andy,

First, no one 'owns' a thread.
Second, I came here in good faith to encourage the participants to carry on with the topic.
Third, with cleaning I mean removing all discussion unrelated to the topic, including this one. No technical posts will be removed, however, some collateral is unavoidable. If you like it as is, fine with me and less work. 🙂
Now, where's my morning coffee...
