Is there a way to do this?

Hey now! I wouldn't know a tech if I saw one in the mirror!

FWIW I have never figured out how to follow data sheet plots. Not that it matters near as much as everyone makes of it. At least not WRT guitar amps. Half the time you'll want to be biased hot or cold anyway. Then there's the fact that once the tubes are clipping, power supply is sagging and voltages are tanking and spiking it all goes out the window. Being able to plot tube charts is a good idea if you want center bias and don't have a scope. I'm sure I could figure it out if it were ever a priority. For now, if a stage is to be biased hot or cold I decide how much so by listening. And as long as you stay within safe operating parameters that is way better than plotting. If I need a stage center biased I just use my scope and bias so that the tube clips symmetrically. Plot schmot.

Well, point it, compared to me you're Mr Electronics. See, contrary to how i may sound, and i know i come off like an idiot much of the time, i'm actually a fairly smart fellow. So i'm able to build and tweak an amp fairly well and come out with what sounds to me compared to the many marshalls i've owned, a very killin amp. But when it comes to numbers thats my achille's heel. I'm sub moronic in that area. So I ask guys like you when theory stuff comes up. I get the routing stuff, gain staging, I get what all the various areas do in basic terms, i know where the danger is, etc etc. But throw a bit of theory at me and I'm a retarded rhesus monkey with a lobotomy. I won't even touch one of those grind organs tho so don't ask.

The split plate load is a neat way to reduce gain and impedance when 1) You don't have a voltage divider between the coupling cap and the following input (could be a mixing stage, etc). 2) When you want to take two different amplitude signals from the same plate. Or 3) When you just need a lower level/impedance signal AND the stage will be run clean. I'll qualify that last one. The suseptibility to power supply noise goes up dramatically when a split load is used. If that stage is clipped it affords noise levels that can reach into the audio threshold.

I actually don't see any sense in increasing gain with a higher plate load only to dumb it back down with a split load. There are better ways to shape tone than increasing the effect of the cathode bypass cap with this sort of circuit. JMHO.

Also, daz's achematic affords post plate attenuation at each stage. Ergo, a split plate load doesn't really fit into any useful criteria. ALSO...

You can't use a split load on the stage feeding the cathode follower because it'll throw the bias out the window.

Daz... Try this: Cathode Bypass Capacitor Calculator

This is just one page. The site offers a bunch of calculators that'll tell you what you want to know if you navigate around.

Are these supposed to be active calculators.?
I just see a schematic, but with no way to enter values for the specific components.
Thanks

yes, and if you can't see the active fields where you put your numbers (to the right of the schematic) you probably need some sort of browser plugin. Java, flash, whatever. But it's all there on both my work and home PC's.
