Gilbert Posted March 31, 2005 Share Posted March 31, 2005 Hi guys; I gettin ready to send the MR71 to AudioClassics for a complete physical and overhaul. However, before I ship it off, I'd like to replace ALL the tubes with some NIB NOS ones. So, can anyone tell me which NOS tubes to get for the MR71. I know there's a variety of different tubes type (6U8, 6AU6, 6CS6, to name a few), but if anyone knows which manufacturer (for which tubes) supplied Mcintosh with the OEM compliment, I sure would be obliged.

Number 9 Posted March 31, 2005 Share Posted March 31, 2005 I have an MR-67 which has a similar tube complement. Most of the tubes on mine are labled either McIntosh or Telefunken. Quote Link to comment Share on other sites More sharing options...
