Re: Maybe I'll understand better if..

...negative bias supply is for the 813 grid , simple as that . Low noise and good stability are important , after all crap / noisy unstable biasing will ruin a quality setup , hence my recommendation for a stack of batteries for the bias , but a separate variable negative supply should do the trick . You will have to check the curves for your required operating point and read the bias value from there .
Hint : when you're out of your depth technicaly , 'tread water' with the knowledge you already have . As this is quite an ambitious project I would recommend breadboarding a single channel rather than building a chassis and EXPERIMENT . Gone off 6C41C ? I've already built mine !
