Love your post! One has to remember manufacturers use tubes that will be reliable in the long term, not so much for sound quality. No owner of tube equipment wants early or unexpected tube failures but these can and do exist and if it’s under warranty, they want readily available tubes.
Most tube equipment manufacturers encourage tube rolling but at the customers expense for good reason.
Have fun!
