Congrats on the BHC. I found the speedball upgrade to be a pretty clear improvement as well. GEC 6080 in the power slot? I recommend the mullard cv4003 for the input tube. Of the few 12au7s I rolled I liked that one the best.
It's a GE that came with it. LOL.
I took the photo as soon as I installed it.
But I quickly kicked it out of the amplifier.
