Chances are that the Miniwatt was made in Herleen which is the same plant that the Bugle Boy was made at. They are both probably pretty close in tone. The main thing to be concerned with is how much life is left in the tube.
Rolling tubes can get expensive. The Bugle Boy is just an older version of the Amperex and/or MiniWatt. People pay more for a Bugle Boy, because they think it is a better tube. I think all Amperex/MiniWatt tubes made in Herleen were pretty much the same quality up until the late 60's.
I took some time to look at that tube website. I thought the prices were on the high side. Plus, they didn't have any pictures. What tubes are you looking for? A GE? I think you could do better on EBAY.
I hope you find a cool one, or don't. whatever works. I have begun to realize i pretty much have the perfect gear for my ears, and it's not gonna get much better. Minor tweaks maybe, but the bas rig will probably stay the same for a while.
Uk oh... as Clint said... "It's a clusterf@ck....a Mans gotta know his limitations..."
