Hi all
A couple of years back my M149 started to be quite noisy. It turned out to be the 6111 tube and after it got replaced by a new one, the mic sounded like new.
I had to pay the bill which was about some $400.
Today an engineer told me the 6111 tube is listed for $6.75
I'm aware of the fact that Neumann uses the best tube out of many, but is that a fair price?

M149 tube posted by Han on March 31, 2004:
Dear Han,
while I'm not the one calculating end prices, there's some things I can say.
- True, you can get a 6111 for a few US$. These are all from those manufacturers we found completely unsuitable for microphone applications, after having test bunches of 100 pcs each.
- In the end, there is only one type we use in the M149, and the price we have to pay for it is markedly higher, especially as the suppliers know that stocks aren't unlimited.
- The tube has to be pre-selected, even with this manufacturer.
- I presume you have a very early M149, which were still fitted with 8254 tubes. In this case, definitely the whole tube module has to be replaced when switching to over to the 6111.
I hope these explanations help...
Best regards,

Thanks, the mic is an exellent mic, no doubt about it and indeed it's an early M149. I've bought it new in sept. 1996
The tube got very noisy after some two and a halve years and indeed the small card where the tube is soldered on got replaced.
I still have the old module and the type of the tube is probably on a place I can't see. I can see AMPEREX and HOLLAND, which is funny 'cause it seems the tubes are made some 60 miles from where I live.
I still think the replacement was very and much too expensive.

I'm puzzled and curious.
