TUBES 6922 pinched waist

Two things:

1. Bad news: the word is that they are almost all monophonic. (amplify environmental vibration).

2. Good news: They cannot be faked. Only Amperex made anything that looks like them.

Be careful of the flavor of the month tube trap. If you can use 6DJ8's, and have new gear, or improved caps, Bugle Boys are about the best there is, if you have old gear, Telefunkins, or the Telsa tubes made on the old Telefunkin machines are about as good as it gets because they are bright and compensate for crappy capacitors in old gear. Do remember though that opinions are like a$$.... and they all stink!

I just installed them a week ago and have no doubt that they sound great. One is a Stromberg, one is Amperex PQ. Soundwise, you can't tell a difference.
BTW - I do not like Bugle Boys. Almost anything else is better. Especially orange globe 6dj8's.

I suggest that you look into some cap swapping. The orange globes are not really a night and day different tube in nature, but if you have good caps, and a sound design, the BB's are about as good as it gets in a 6DJ8. Of course tubes are not linear, so they all suck compared to good FET circuits in the accuracy department. That said, coloration, while not accurate, can be more pleasing than an accurate reproduction...
