I think it's pretty neat compared to some of my previous builds. But when I cram that much stuff into a chassis I guess i expect somewhat of a mess
I once repaired an an early model Fisher FM100 tube tuner, point to point, looking like they sprayed in a quart of molten solder mixed with assorted parts. The theory (as I understand it) was all about randomizing strays. It worked well (was reasonably quiet) but made you laugh the first time you saw it.
Some more pics of my Velleman P8011
there are two for sale in France, cheap (300 €)
Here is the video where I show a negative feedback. Wavebourn - Edelweiss-3 demo | Facebook
Explanation of soft clipping, when after 1/2 of power it starts deliberately distorting mimicking "too loud" sound: Wavebourn - 6.9W | Facebook

latest build - GU-46 single ended
Here is my latest build, GU-46 single ended stereo amplifier.
Power management (start up and shut down) by Siemens Logo 8 aequivalent.
Currently with with a 12hg7 driver installed (might be changed to some other tube later).
4 5C8S rectifier tubes per channel.
Circuit optimization ongoing.
Total weight of iron approx. 90kg, capacitors and electronics approx. 12kg, industrial aluminium profile housing and lexan/plexy approx. 55kg

thomasweissbach, I notice that there is a screw post that is not perpendicular to the base -- though this is acceptable to my Canadian standards, someone of your calibre should not have to endure that engineering torture. Please send the amp to me and I will find a good home for it.
Just kidding!
That is an amazing build and what a build process too! However, this makes me wonder, what is your next planned tube amp going to be?

This will most probably be the last big build - I had to promis this to my wife.
I was told to sell my two bi-amping 6V6 quad monoblocks for it (space reasons). The big 6L6 quad stereo amp ist still here.
My wife was also the reason to make it that massiv - so she can't cary it to the junk yard.

What’s the expected OP power?
Got a pair of GU-72, but as I am moving to a new home this Spring, that project has to be on hold.
PLC controled 0.0 this is the next level!
Awesome build! Félicitations c'est très beau!
