I have a Primaluna Dialogue Premium HP HI-FI amp. I have heard that some of these tubes are made in Russia or China, while some are made in east Europe. The east Europe ones are far superior,so iv'e been told.Is this true, & which ones do you sell? My amp takes 8 power tubes, are these really an exact modern production reproduction of the NOS Mullard XF2 dual getter tubes,& would they be a great fit in my Primaluna for home stereo reproduction? I need to know the truth before i purchase! Also,do you sell matched octets? Thanks, Mike

Why do these only come is pairs?

This is the way we get the tubes from Groove Tube. If you want a quad you can order two pairs and we will try to match up two pairs depending on our current availability.
I bought a set of el34;s but they have 8 pins, the original have 7. If this a problem?

If the tubes you are replacing are El34's you should be fine. The El34 has an 8 pin pinout.
Are these the same as the Groove Tubes EL34-M? Or they two different tubes? The description fits the EL34M, but they're labeled EL34. Thanks
