Vintage U48 very rare less than 800 produced, recent tech inspection shows only the resistor in the base has been replaced over the 65 years. This has the original K47 capsule, a VF14 tube, also included are a Blue box, aftermarket new shock mount,and Telefunken cable & power supply. I can offer to replace the Telefunken PSU with an original Neumann NG PSU upon request at an extra cost to the buyer, if desired.
