 They're still being made, mostly in the former USSR.  After Mullard
 stopped producing valves in the 1980s, a company in the USSR bought
 the whole lot up and shipped it across.  If you buy a Sovtek ECC83 or
 EL34, it's exactly like an old Mullard one.
 
I buy 6B4G's,5889's,6BQ7A's and throw in a 12DW7 and a 0B2 for good
measure. :)
