Now that's what I call a breadboard! Beautiful work!
Just need more info. Are they TV sweep tube outputs? Or EL34s maybe.

100TH singel ended triode tube amp.
Rectifier WE249C mercury vapour.

This is how an no compromise amplifier look like, mercury rectifier in a separate chassis.
Congratulations, if this would be lighter and smaller I would built one myself.
Can you share the schematic?

Hi @Shef , you are using tube sockets which allow screwing wires to the pins. Can you point to where you got them?<Posted a great breadboard picture>
Thanks

Search for "octal relay socket"
Thanks @quadtech , using that search term I even find them at Mouser 👍Search for "octal relay socket"
I am not able to find a similar thing for Noval tubes, though. Don't they exist?
Another AI rendering?, yep....the second image is a dead giveaway as it should be a "one point perspective", the front panel with its nine-millimeter thickness...you should see the far side of the panel angling to its vanishing-point.

The poster said that it is a "300B Design Scheme". Doesn't that communicate it is not the actual build?
A slightly better pic of my 807 class A2 monoblocks. Still waiting for cathode decoupling caps on the input tubes (6SJ7( but they run just fine without them, although the gain is very low.
The holes in front of the grey transformers bothers me a bit: I have two nice potted Triad chokes that were supposed to sit there but one turned out to be open circuit and finding a replacement was more or less impossible. The best thing I could do was to put some metal mesh there to make it look like ventilation holes...

It's not an AI design, it's a computer modeling scheme. Production is in progress.
Nice! What did you fill the aluminium plate with?
I made a few mistakes on my last build and was thinking of gluing some screw heads into the holes before powder-coating but filling and sanding would be much better.
My collection built in just four years, the rest being sold.
