I was speaking mostly of the kt66 which you may have to change a bias resistor,but I found those and the 6L6gc black plates to incredibly good in that circuit because of the good driver characteristics. EL34s are limited at a both ends of the spectrum as far as detail and even tho the mids are fine,by comparison to the kt66s an the 6L6gcs they come up short in most instances..You are talking to guy here that owns almost every vintage tube amp ever made outside of Western electrics.I have been there done that.I'm not saying to discard EL34s all together,but I have a pair of nines that I inherited that I have packed away and I also have an 8,which is similar to an 8b and both are really nice with the kt66s..I did have to change a bias resistor in the nines for added range but,it still biased el34s just fine..
THe kt77s are the best EL34 based tubes I have heard..I have everything from XF2,xf1,metal base Ampoerex, sq getter Amperex. five staple Telefunkens,4 staple RFTs,and many more such as SEDs..Here is a photo of a few..I can tell you honestly,they don't touch the Genelex kt66s in the 8b with a bias tweak.I could kid you all day long about how good EL34s are if you want me to..I have them all and you are welcome to come and test for them for yourself.THe best EL34 are the KT77s and thats my opinion..They were designed more as an audio tube and not as a guitar or industrial application tube to handle higher voltages.
