RE: Raytheon 12AX7A US vs Raytheon 12AX7A Japan



Please save your money........, say Japanese versions are Hitachi, whom bought out Raytheon during the mid 60s, and having owned other Japanese makes from the likes of TEN Kobe | NEC ( set up by Western Electric during the late 40s ) | Toshiba | Matashita(? Aka Japanese Mullard ) which are remarkable sounding tubes in their own rights.

All that to say Hitachi tubes on a whole from this period, sounded rather hollow sounding throughout. Raytheon on its own......., let's just say to my senses is well behind brands like RCA NOS 1950-55 Long Black Carbonized Plates | Sq Getter | Sylvania LBP | Westinghouse from the same period are all outstanding, as are the Ken-Rad's made between 1947-49, provided one can find quiet ones that is?.
