Update....
I recently had a quad of not so new old stock GE 6L6GC's thrown in in a deal, and even though one tube looked a little weak, they sound great in my custom amp running the 19's....
I also have made what appears to be potentially the deal of a lifetime on some 50+ year old speakers. I will wind up paying more for shipping than the speakers cost. I'm not going to say more until they are on the moving truck headed towards my 3rd garage bay, but I couldn't hardly sleep for 3 days as I was waiting for this deal to go through....
More later....
