I need about 20 12AX7's for my R-388's and other equipment.  Epay is crazy.  
Is the Russian Double
Triode Tube 6N2P-EV a legitimate viable substitute?  What about the Svetlana 
12AX7's sold by
Triode Electronics?

Keep in mind the 6N2P tubes have a 6 volt filament. You will have to rewire 
the filament line going to the 6N2P to 6.3 volts to get it to work. May cause 
problems down the line if the mod is not clearly documented on the chassis or 
near the tube socket and someone tries to plug in a 12AX7. May be more trouble 
than it's worth to modify a radio to use them. 73 Todd WD4NGG
