Mullard GZ34 5AR4 Rectifer Vacuum Tube Tests STRONG with Box F31 X8I
Her is a beautiful Mullard GZ34 5AR4 tube. There is no branding on the glass, but it is etched with the code f81 x8i which i believe to be a Mullard manufactured in the Blackburn plant in 1958; one of the most sought after Mullard GZ34’s based on the forums. This tube tests very strong and is in aweso.e shape with an in tact center locator and shiny, rust-free pins. The box appears to be period correct but is probably not original as it is marked “used”. The box is very delicate and needs to be handled with care. please see the pictures for construction details and other specifics as what you see is what you get.
