GZ34 Valve

The GZ34 = 5AR4 has, with good reason, always been considered the "Princess" of rectifier valves, especially since the 1950s with the queen mother or the first version with the "metal ring" in the base. The massive production of this tube, in those years, was done by MULLARD, MAZDA MBLE and PHILIPS, always under Philips hegemony. This is an excellent VERY RARE PAIR of GZ34 (CLICK for info) MAZDA production, NIB, genuine made in Belgium, f33 series, with L code, in 1962. The valves are in Philips box, probably NOS, excellent cosmetic condition, electrically perfect ! The GZ34 L Mazda stands out for its great robustness, smooth plates, double DD-getter. Ideal pair for HIFI and HI-END monophonic systems. TEST over 100%, complete balancing and coupling (even for codes!).
