~Tube Health and Performance Analysis~ ****

These 437A tubes have been actually tested! The 437A is difficult to test based on the Magnoval pins and the 437A's very high transconductance, so we had a custom test lead set made specifically for the 437A engineered to use with a Jackson 648s. 

Tube tests as a new tube should (approx. 111% rel. µmhos). No shorts/gas/grid issues. 

Brand new, tested, and guaranteed. 

Each tube is guaranteed to be as described.  

This packaging is only the original corrugated square from Western Electric. 

The auction is for a single tube. More great tubes will be listed soon, so check it out! All shipments include a pair of nitrile examination gloves for installation.

Get these before they are gone!
