It looks like there's a mint-used Heritage available near me in Tokyo for about the same $2500 or so I'd spend on a 60s model. It seems like there's so many old B-15N's that I wouldn't be surprised if they don't appreciate in value much. If that's the case, then it's really just a question of tone and the vintage vibe. While there's a few really nice-looking B-15N's for sale around the world, the good-looking ones won't ship. I assume any of the cheaper ones will need work to combat rattles; may need reconing and/or recapping and/or re-tubing. And the local vintage ones are really fairly corroded and rusty. On top of being all rattle-free and not needing any work, the Heritage also has the appeal of the '64 and '66 circuits available. My main question is I guess tone: is there anyone who is familiar with 60s B-15N's, and has played the Heritage model, and does not think the Heritage lives up?
