Lawson Quick Change™ Capsules
Lawson microphones feature Lawson's Quick Change™ capsules. Quick Change™ capsules are universal and interchangeable with all Lawson microphones in the Quick Change™ series including the L47MPII vacuum tube mic, L47FET, L251 tube mic, and L251FET. Any of these models will accept the Quick Change™ capsules/head assemblies from all other models.
For example, an L47MPII tube mic can be converted into an L251 by simply purchasing the L251 Quick Change™ capsule/head assembly. Remove the L47MP Quick Change™ capsule from the Lawson Vacuum Tube Electronics and plug in the L251 Quick Change™ capsule. The conversion is complete!

The L47MP Quick Change™ capsule is pictured on the left; the L251 Quick Change™ capsule is reclined on the right and shows the connector that plugs into the Lawson Vacuum Tube Electronics and/or Lawson FET Electronics.
