  It's impossible to have a full wave rectifier with '2 pins' ! 5V4G and GZ32 share identical pinout and are interchangeable in most applications

  All 5V4GA tubes I have ever seen have an octal socket and usually 5 pins with 3 blanks. 5V4GA are all rated the same electrically.

  The only ones I have had reliablity trouble with are the Dario GZ32 when the supply voltage was 400-0-400.

  Get a nice pair of RCA 5V4GA. The true Mullard GZ32 are getting pricy, but more power to you if you can swing them.

    Hi Chris O!
    I see someone lists a 8 pins version of 5V4GA on Ebay. That's why I confuse.

    Regards,
