Good day, I am new here and this is first post. I am a newbie and have been extremely enamored with tube amps. I am in the process of building the Pete Millett 50W mono engineers tube amp. I am looking at the printing on the PCB with the pin breakout. The PCB (original version) with the solder in tube sockets in all of the images, has the tube sockets soldered in on the back side of the board. What I am finding confusing is that when you place the socket on the opposite side of the board the pin configuration gets reversed. I am imagining that this has been thought through and operation will be correct. Can anyone clarify this for me please. My apologies for asking such a simple question. As I frequently read the boards there are truly many brilliant minds here and I feel I may be asking a simple question. Thank you again for any info and I hope to continue learning as I go here. Here is link to page. http://www.pmillett.com/DCPP_MB.html

It looks like this has been taken into account on the board. Looking at the component, or "down-facing" side, the tube pins 1 and 12 and 1 and 7 are properly oriented if the sockets are soldered to the opposite, or "up-facing" side.
That's what I would expect from Pete. Anyway, @izahner, just follow a couple of pin connections to other components and compare to the schematic, that would give you the confidence. We can all speculate but you need to be sure.
It's a skill that will come in handy umphteen times when your amp doesn't work and you need to trouble shoot.

There's a dedicated 50W monoblock thread here just in case you haven't seen it. https://www.diyaudio.com/community/threads/50w-monoblock-engineers-amp.302586/
Could be some valuable info contained therein for anyone building this amp.
