Re: Tung Sol EF86
My NOS RFT is doing beautifully. I was told when I got it, to give it a full 24 hr burn with no signal running. So far, that thing sounds just amazing with no issues.... A guy off the PP forums told me that these were the most stable that he knew of.
We shall see if they can make a new one that sings. A stable version of that tube would a be gift from the gods!!
