BH is here! I assume I don't have to bias the amp to use the stock tubes, right?
Edit: OK, I guess since I don't know which tubes were in which socket, I guess I will have to re-bias the amp.

Also, is the trimpot adjustment tool supposed to be in the box? I missed it. Can I just use a very small flathead screwdriver?
Another stupid head-fi-like question: Can I listen to music on it while letting it warm up for an hour to do the second round of rebiasing?
