JJ GZ34 / 5AR4

JJ GZ34 Beskrivning från Eurotubes: Factory description: Special plate alloy material and improved design for better performance, stability and life. My observations: This tube is as close as it gets the old Mullard GZ34 that we all know and love! In fact the plate construction looks to be almost identical to my large base Mullards with the straight edge plates. I've been using these in all my old SUNN amps now for over a year with great results. They seem to know just when to give in to get that wonderful rectifier sag. I also use these in Mesa Dual and Triple Rectifier amps in place of the stock 5U4's to get a little less sag but to maintain that rectifier sound. A perfect tube to replace the chinese or sovtek 5AR4's that we have all grown to dislike so much... The JJ GZ34 will get your Deluxe sounding like a vintage amp.
