Hello all,
Because I'm fairly new to tubes, i was studying a lot of different schematics the last few months. Now i stumbled across this ecll800 schematic: http://www.audiofanatic.it/Schemi/Tipo/Valvole/finali/pic_finali_PP/ECLL800_PP.jpg (fig2) and i can't figure out why there are missing the 2 grid stoppers and 1 grid leak resistor in the output stage (in comparison some other ecll800 schematics: http://www.radiomuseum.org/images/tubeenvdiag_klein/ecll800.png http://www.jogis-roehrenbude.de/Verstaerker/ECLL800-Schaltung.jpg ) . Am I just too stupid to understand it or did the designer of the schematics missed something. I would really appreciate it if someone of you could clarify things for me.

There is a grid leak missing from the first circuit. Must be an oversight.
Grid stoppers are good practice, but can sometimes be omitted without harm.
