Why should your view, opinions, bias, etc. force others to do things in a way they don't want to? Why are you so dug down that you can't enjoy what you see in common because what you see differently drives you crazy? It's just a hobby.

I like the idea of using diodes. If I understand them correctly they should not produce any noise or distortion when not conducting so that the are inert in normal operation.

It might be fun to use strings of LEDs (protected by Si diode against reverse bias) for a visual indicator of being activated.

Because they did not plug those tube regens into low-voltage components like opamps. The diodes are to protect modern low-voltage components.

Would this be right? That is to accomplish the clamping and protect the LED...

We're asking a lot from those LEDs in series with reversed Zeners.
Just saying,

Probably not worth it just for the bling.

Where and when I wrote that he must do what I said?

Call for medical aid, please. You are ill.

So, you only offer non-binding criticism of SS used in tube circuits? Why say anything then? I am not trying to attack you, in fact, that would be the opposite of my point
