Brand New In Box Matched Pair (2) Genalex GZ34 5AR4 U77 Rectifier Vacuum Tubes. The Genalex reissue GZ34 / U77 / 5AR4 is probably the best new production GZ34 on the market. New Sensor corp put an incredible amount of effort into copying the original in both construction and tone. Looking for a better tube is pointless. They got it right down to the classic saw-tooth edge plate construction.
If you need stable DC voltage, look no further. It's wise to invest in a good GZ34 as these rectifiers run hot and the cheap ones burn out quickly.
