The death of one of the GE 6550's in my Sunn bass head almost brought tears to my eyes. I can't afford a matched pair of NOS 6550's. I reluctantly bought a pair of these. I was really surprised with how good these sound. My bass tone has a really good bottom and is punchy. And the price is really good.Will these tubes last for thirty years like the GE's? Probably not. But these are a great inexpensive replacement.
