It was bizarre reading them back to back.
If Aspen says "if you have the early tubes in your SVT, by all means change immediately to 6550s" -- and he does -- then Ken says "if you have 6550s in your SVT, by all means you'll want to change back to the early tubes".
Aspen also championed the B-15S as a great amp that's less farty than the originals, while Ken turns up his nose at it and says the earlier ones are more toneful (of course those are the ones he worked on at Ampeg).
After trying both I decided the B-15S with its extra power and mass -- physical and musical -- was the one for me. Though like I said, an original B-15N (or the 50-watt B-15ND or B-18) would look and sound great sitting next to it!
