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!
