Questions about retubing BAT VK-75SE

I ended up not using triples. Went with matched pairs, but use one pair on the left moost 6sn7 spot for the left channel, then the other matching on the left spot for the right channel, then the next matched pair in the 2 middle 6sn7 spots and so on...

I'm with newbee. If the 6sn7's are working...don't worry about the cracks...

yes, they do. However, you can change the sound slightly with new 6sn7's and the tube next to the 6h30s'. I used RCA 6sn7's and it's softens and sweetens the hights somewhat.

Matching is important on the 6sn7's, as the are part of a balanced gain stage...matched triples for each side.
