TNT Mic Pre Retube Kit Version B
This kit is only for Manley TNT MIC PRE's with the serial number MTNT232 and up.
(1) of 12AT7 tube for input
(1) of 12BH7 tube for driver output. These units cannot take a 6414 to replace 12BH7 like our other units can. Be aware that some tube brands are subject to change over time and may not match the pictures shown.
UPDATE: We have replaced 6414 tube with 12BH7EH type as of October 2013 on most of our products. There are limited quantities of 6414 GE or RAYTHEON so 12BH7EH is what will ship by default.
