Looking to swap a Beesneez K8 for either an M7 or a CK12. Capsule was installed in an 87 circuit that never left the bench, has probably seen 4-8 hours under power, its in mint shape. Circuit was torn down and repurposed and this capsule has been on the shelf for a couple months. Would be delighted to swap this for a capsule more appropriate for the circuit Im working on. Shoot me a message if you are interested, thanks!
