GZ34 valve

The GZ34 = 5ar4 is, with a view of a view, which has always been considered the "princess" of the straightening valves, especially starting from the 50s with the queen parent or the first version with the "metal ring" in the base. Massive production of this tube, in those years, was made by mullard, Mazda MBble and Philips, always under hegemony Philips. This is an excellent pair of very rare GZ34 (click for info) production Mazda, NIB, genuine produced in Belgium, F33 series, with code L, in 1962. The valves are in box Philips, probably NOS, excellent aesthetic conditions, electrically perfect! The GZ34 L Mazda stands out for its great robustness, smooth plaques, double DD-Getter. Ideal couple for HiFi and Hi-end monophonic systems. Test over 100%, complete balancing and coupling (even for codes!). Equivalent: 5ar4 = cv1377 = 22s22c = gz34s = gz34str - replaceable: gz32 = 5v4g = 5u4 = gz33 = u52
