What a big vacuum tube! Single Ended Mono Block Power Amplifier

[egellings]

I'm afraid you won't get any X-rays from such a tube GM70, GM100, 845, 211. There is a video on YouTube on how to get x-rays at home. For this, special tubes and very high voltages are used.

Agree. Anode voltages used in any audio tube amp are way too low to cause x-ray emission.

Yeah, this thing takes what, 1.7kV? Nowhere near x-ray territory, which as I recall starts around 15kV.

Yup. It was a problem in the (early) days of CRT color TV, with 25 kV on the anode, requiring the adoption of leaded glass in tubes like the 6BK4.

This thread became political and that is not permitted here. Warnings have been issued. Many of the participants knew better and posted anyway. So a good thread about Audio Gear got shut down because it turned into a Political Conversation. If you want to talk politics, go join a site dedicated to that. Not here please.
