So i just installed the speedball, all measurements where on point.
Just plugged in, everything works. Just that there is a buzz in right channel, for like 2 seconds, dropping out for half a second, coming back again. One part on the board looked quite crappy, before i soldered it. Could it be that? Buzz starts once tubes come to temp, after few seconds of turning it on. I shorted the rca plugs, and sound was still there. Does get louder when i turn up the volume. There is also background noise at higher levels, but i assume that is normal. Although it might be more noise than before, not entirely sure.
I took a picture:
