I know I should walk away but I have a line on a B-15s. What I really want is a early 60s b-15 but as it's been said, you can't always get what you want. Allegedly it has the Altec speaker. How B-15 is this amp? I know it's a PC board and I'm not feeling that. But PC boards are a fact of life. Should I stick with my Univalve or go for the real thing?
