If you can find some ...................6SL7 Kenrad chrome cylindric plates , ECC35 mullard and CV1985 ..........;the latter has even glass tube sleevings as protection on the wiring inside as seen in some 845 W also ( NU)....... People who may listen principally to classical music may prefer european made tubes , with some exceptions like RCA etc.......
I need a schematic for a tube phono preamp for pre-war 78rpm records (not RIAA).. Turnover Rolloff Columbia (1925) 200 Hz (250) -7 dB (-8.5) Any ideas where to look? Thanks
Sorry 78's are not my specialty, if a simple Google search doesn't work, you may need to contact your local Ham Radio club someone will almost certainly have a schematic for what you need.
Another GREAT EL 34 is the genuine NOS made by the former TESLA factory .........not earlier JJ that rebranded their EL34 with the Tesla logo ! >These are as good asd the Mullards ........some may even like them a bit better ..... I have a lovely experience with those tubes , pity I sold most of them in the nineties.... And their E34L was the greatest bass performer I ever heard ..............JJ makes copies of the E34L but they are nothing a like with original Tesla and the sound is not the same !
Jim, this is a very good video. You have explained a difficult subject very clearly
Thank you for parting with gems of knowledge

Yes the true vintage Tesla's are good sounding tubes, unfortunately they have proven to be much less reliable than almost any vintage EL34 I can name.
Beside Mullard , Tesla, RFT .............I like the glorious sounding ( almost like a triode ) nos 6CA7 GE fat boy ............woawwww!
