The changes you should get from the break-in on a NIB tube should be quite large. I found that it took about 150 - 200 hours to see some real results. I would love to hear how your 350b's turn out.

I have a pair of Mullard 37's that are terrific but are tempted to check out the 350b's with all I have heard from everyone.
