I just noticed a boo boo, if you look at V4 it is missing pin 1. I will have to get another socket. Faster to just order one than to contact the seller.

Pin 1 on V4 is actually not used for anything, but I am guessing it is still better to get a new socket so that the tube will ultimately be held in tighter.
 
If you look at how the pins in the sockets are held in place you can see that sometimes they will come out rather too easily. I've replaced pins in sockets a few times and bent the retaining bit a little more to help stop it from coming out again. There is a small section in the middle of the pin which is pushed out to make a kind of clip. you can push it out a little more and it holds in place a bit better. I think i used a pin or something. it's fiddly!

I like the pale brown Belton sockets for both octals and 9-pins. Just be careful when you splay the pins on the octals because they snap rather too easily. That's not a problem in your amp because it's all 9-pins, but believe me, if you like this amp it won't be the last you build. :cool: BTW it is a good idea to splay the pins a little - ie bend them away from each other, especially on the power tubes, to help prevent arcing between pins. It also helps prevent them coming out with a tube.

I appreciate the advice, thank you so much. I doubt it will be my last amp, but will probably be my last one for a while. I miss building pedals so I have quite a few to catch up on. I just needed a change of pace.
