Mono Mic Pre Retube Kit Version B
This kit is only for Manley MONO MIC PRE's with the serial number 40MPB154 and up. Includes (1x) 12AX7 tube for input, (1x) 6414 or 12BH7 tube for driver output. 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.
