Came across a Vintage Modern 2466 from a friend. He's letting it go for a good price. And i always wanted a VM. Heres the thing...it's a B-Stock. He bought it like that. With B-Stock amps..anyone familiar with them? Are they a lot of work? Will they have more problems? Will i be getting myself into something that i don't want to? The amp comes from a good household and it wasn't used that much.
