Please HELP !
Please neglect the above schematics - after careful reading of the thread I made some important changes but after replacing the cathode resistor with a red diode /ancient one from East Germany/ the voltage across it went to around 2 V /depends on the tubes applied/. On the resistor of the second cathode it stays at 1 V /190R/.
Please suggest shall I try to go for a lower resistor value in order to equalize the voltages or something else ???
Thanks in advance for your help,
Ignat

I did not mean to offend you, but I feel you don't like my advice.
As I said before, bypassed version of SRPP gives more distortion, and the dominant noise source is the volume pot, with higher gain you also have more noise, even when bypassed SRPP has less noise than unbypassed version.
Just wondering if putting bypass cap or not
According to the simulation, adding a capacitor also reduces the THD(0.01)% and increase the gain.
What are the disadvantage?
thanks
