Be very careful of any seller that sells "NOS in white boxes". What this usually means is that the tube tests as NOS but is most likely used. I am not sure if one respondent was suggesting that there exist 6SN7s that were made by Amperex but just for the record Amperex never made a 6SN7. I have seen Amperex branded 6SN7s but these were made by GE. Be very careful of tubes branded Sylvania Bad Boys. The Bad Boy is a great tube but is very specific in construction. Tall, 3 hole black "T" plates with bottom foil getters. Most I have seen were made in late 1951 and in 1962. This is the only Bad Boy made and many ebay sellers are selling Sylvania tubes as Bad boys which are not and quoting an online tube seller who knows (or should) better. Be careful.
Tube rolling Question
Hello Tube Rollers
I recently bought my first tube preamp (Blue Circle 21.1). I've noticed I am need of new tubes as the tube whoosh is considerably more noticeable now than 6 months ago. The amp comes with Electro-Harmonix 6sn7 tubes which I appreciate and dig the sound. I will certainly replace these with a the gold pin model as I like the sound profile. Here's my question:
What other tubes might you recommend for a different "flavor" of sound, and just to have fun with. I am a poor audio guy so please no recommendations for tubes that will cost more than preamp.
Thanks in advance.
