Got the idea for this from Frogfur's JBL thread. Let's see what gems we have in the MLP community. I have a bunch, but I'll start with my favorite guitar speaker extant. The old Altec 417-8C alnico. I bought a pair of cores and sent them to Great Plains Audio to be re-built. Those are the guys who bought all the old tooling and parts when Altec went bust. They are the final word in vintage Altec. The 417-8C has the good qualities of the JBL "D" series, but without the downside.
