After reading countless posts I have narrowed my choices down to Tung-Sol, Winged C, and NOS Phillips 6l6wgb. I have a 1965 twin reverb that I want to retube. Can anyone offer a good opinion on these or are there any others I have over looked. I found a couple of great deals on the NOS phillips for under a hundred. Also anyone have knowledge of making an ebay transaction with someone from Canada?
