I have done some searching and wanted to get some opinions. It is time for new power tubes in my SVT. I would love to go the NOS route or buy some original Winged C's. Given the recent prices, that isn't gonna happen. Out of all of the current production 6550's, in the reasonable price range, ie Tung Sol, JJ, etc, is there a clear winner? Just want some opinions and info from those who have used the recent stuff.
