I was researching 6C33C tubes and found this thread.
Has anyone noticed a sonic difference or quality difference between 6C33C tubes from Novosibirsk or from Ulyanovsk? I often find listings for 6C33C tubes from these areas and don't know which one to get. I've been told the 6C33C-B were made for the military and the ones to get are from the Ulyanovsk. I don't want to try a set of tubes from each place because it gets very costly with shipping.
Thanks
