I like the round over you put on the top edge of the base.

Thanks Paul, the base turned out great pics don't do it any justice. This thing gets very loud at about 9 o'clock on volume guess I need to turn down volume on computer. Was wondering what big tube I have all I can find on it is RCA 6A57 and 7552 which one is it?

It looks like an RCA 6AS7G.

The reflection of the lamp base gives a hint of how smooth the finish is. Nice work. Did you add the "picture frame" on the top of the base or is it all router work?

Did it with a router. The base was the hardest part to get the look i wanted. Had about three costs of poly and I goofed so I sanded it back down and started over. So now there  is i think 8 or so costs of poly.

have you see the crack FAQ on how to add the 75k/33k resistors to the pot to attenuate the signal a bit more? I had the same issue with not being able to turn past ~8 and it also having the issue of poor l\r matching at these lower levels.  Doing this did the trick.

Also your build looks beautiful!

It doesn't take a rocket scientist to hammer out that mod, but it might help?

You'd think after trying to find that picture/how-to on at least on 3 different prior occasions I'd remember it was in the FAQ....but no, not even today. Probably not tomorrow either ;)
