NOSValves Posted February 21, 2016 Share Posted February 21, 2016 By far my go too is the mighty 5AR4/GZ34. I also love the even mightier CV593 (real) don't mistake it for a consumer grade GZ32 they are very different in performance. The CV593 can take a huge beating.... I ran the Tungsol KT-150 George jetson tube past its limits in current in my VRD's (red plating those bastards) with a set of these and the voltage didn't budge... I was shocked...I figured I would have to install SS rectifiers to do it! Hold onto your wallet to get the real deal Mullard's though. By the way the KT-150 is not worth the price of admission it sounds sterile compared to my go too KT-88...but it is tough as hell as is the KT-120. I'm not one to believe rectifier make a huge difference in sound because of the rectifier itself. Changing type will indeed make a difference in most amplfiier but its from the electrical voltage and current change. IMHO opinion the best rectifier for an amplification is the type it was designed for.for evveryday use the CV593 is not used in my VRD's for instance. The 5AR4 sounds as good or better. 1 Quote Link to comment Share on other sites More sharing options...
