How is the quality of the Decware branded EL-34 and 5U4G tubes that ship with the amps?  Anyone know the manufacturer?  Just received my Rachel today (34I.5), and wondering how the tubes stack up to other makes.  Thanks for any help.

Currently using a 1951 Zenith 5u4G. It has a bottom D getter and the glass and pins etc are spotless. Tube base yellow branding etc just like new. I have the original Decware branded 5u4g stored in box to keep. As posted above, I believe it is a Linlai tube.  A NOS rectifier was recommended to have on hand. I have a couple of other rectifiers I purchased (NOS), but I am all good with this Zenith. (may be manu by RCA) And was a cheap one at 14 dollars. Meters still read exactly as they were when we received and plugged in the zen first time~ Still playing almost every evening since new. Love it!!  Take care~Mike
