No, zul, I'm kind of a noob, haven't tried too many rectifiers. The 5U4GB's seem to make the power tranny run hotter than the 5AR4 types (I hope I'm not putting too much stress on various bits with the sudden power rush and slightly different ratings of the 5U4G/GB vs the 5AR4...considering Steve has the 5U4G on the schematic, I doubt it). I could be completely mistaken, but they seemed to sound better, too. I haven't had the pleasure of RCA 5U4G big bottles. That tube is favored by many Decware users. I do have a chinese 5U4G, which I also prefer to the Sovtek 5AR4.
Sorry, not much help am I? I told you I'm a noob! Hey, I'm cheap, and at least I've found a tube dealer that doesn't ask for your first born. That merchant I mentioned before probably has whatever tube you wish to try in stock. You've got me curious, I may call myself and see if he has any RCA non 'B' 5U4G's and for how much. If I do, I'll post what I find out.
