Do you guys have your power tubes matched? Is there a reason, or is it better in some way to have power tubes matched? Also, does it matter if the amp has only 2 tubes? I’ve heard people say some totally different things about this. I’ve seen people say there no reason or benefit to have them matched. At least one person claimed that an amp could/would actually sound better if the power tubes were not precisely matched! And the other sides argument is they should always be matched. Is there a consensus on this here?
