Does anyone know where I can find a replacement tube for this mic? Mine's going bad. Websites tell me its a 6C315P tube, but there seems to be no info or availability. Is there a equivalent number I should look up? If I can eventually find a replacement, what brand would be a good match?
 
The only place I could find mention of this problem is in a google search that brought up another forum:

http://www.firebottle.com/fireforum/ff.cgi?cmd=vt&fid=misc&tid=109992722331QnD3S

(Go about halfway down the page)

They say that the tube is in fact a 6C31A-P, which I also cannot seem to find on any websites, nor on the major tube sales sites.

I'd say your best bet is to call customer support and see if there is a known type that might replace the valve in that mic.
 
The American number for that tube is the EF95, which can easily be found on eBay and a lot of tube websites.
