Recently finished my first SE 300B amplifier, happy with the final result . Worth every cent.

Self Inverting EL84s in Ultra Linear Mode.
That is the first time I have seen a self inverting UL output.

And, another great 300B amplifier.
(Show, Tell, and Listen at Decibel?)

I really enjoy seeing designer's and builder's good amplifiers on Tubes / Valves.
"It is hard to argue with success" . . . successful amplifiers.

For those who prefer a powerful device..., PushPull fixed bias Kt88 or 6550 monoblocks.

I asked the same question after seeing one of alex's previous immaculate builds. They're insulated crimp bootlace ferrules.

Thanks! These are awesome

Plenty on your preferred online shopping site along with the crimping tools.

An interesting night-time view of my double quad 6550 2x115W amp. A couple of tubes nicely have a very strong flourescent blue on the inner envelope, why don´t the others show the same when all tubes are well matched ? trace impurities ?

In my experience, even if the tubes are of the same manufacturer, same vintage, and matched . . .
They often do not all have the same glow inside the envelope, same glow shape, or any glow at all.

Your guess is as good as mine . . .
Your Mileage May Vary

All the above... too many variables.

6N13S PP tube amplifier. Many thanks to @artosalo for technical support. He helped me a lot during the building stage.
