Could you assemble also a closely matched octet for me?
Asked by Anonymous on May 10th, 2018.
Yes, add two quads into your cart and checkout. Towards the end of the checkout process there will be a notes section where you can request the two quads to be matched as a octet.

Product Reviews
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.
