Does it sound BETTER with the matched tubes?
I tend to treat my tube amps as .... if it ain't broke... or... if it sounds good... is good.
But, I understand your concern.
I would probably get back in touch with the retailer and voice my concerns. Etc
Thanks for the reply. The amp definitely had more heft with the KT88’s, although I am not sure if it was just because of switching from 6550’s. The amp sounded great before. More than anything, I guess I am more concerned about a failing tube. I am going to throw the 6550’s on my tube tester to see if there is anything amiss. If they check out fine, I’ll just chalk it up the factory throwing in whatever tubes they had.
