Two channel amp with EF86´s. Mixing resistors size.

Hi there!


In the attached schematic, do you think i picked the right value for mixing resistors?


After the Send/Return jacks i have a 1M resistor to ground. I know that with both volume pots in both channels just before the 12ax7 there is no need for it, but if i use the amp as a tube "power amp", that means, connecting the signal to the "return" jack, i will need a grid leak resistor. If some one have any idea to make it better without loosing signal due to the voltage divider, i will thank you a lot.


thanks!

If you make the mixing resistors 220K you will have less signal loss due to the voltage divider with the 1M. Isolation between channels would still be good too.

Thanks!  I´ll give a try!
