I recently sold a pair of EML 45 Globe Mesh for $700.
A new RK 5u4g is about $500 new, about $400 lightly used
A KR 5u4g is about $375 new, about $300 lightly used
Suppose an Anniversary 5u4g is between these
I still have a KR 5u4g lightly used in my Pacific for $300 if interested. The RK is better, but not by much.
