PSU question

[daz]

I hope i can word this right so that it's clear, but here goes. lets say you have 3 nodes in the B+ rail after the screens. And lets say the total resistance for all 3 dropping resistors is 30k. now lets look at 2 different scenarios both with a total of 30k, but distributed different.

Lets say for example the PI and V2 nodes both have 5k resistors and V1 has a 20k. We'll call that scenario A.

In scenario B we have the PI and V2 nodes each with 12k resistors and V1 has a 6k.

So as you see the total resistance from the PI node to the last node at V1 is the same and *as far as i know* the voltage should be the same at V1 in either scenario. So here are my questions

1-IS the voltage going to be the same at V1 in either scenario?

2-will the tone of the stages at V1 be the same in both scenarios? And i mean WITHOUT consideration of the 2 nodes before it and how they affect tone with thier different voltages in each scenario. Just V1's tone....for example if you put a line out from v1 to a power amp. would the tone be different in either scenario?

1. Not neccessarily, due to the differnt internal resitance of each individual stage.
2. If the voltage is the same I'd say yes

This isn't really a voltage divider like a volume control might be.

YOu may have the same 30k resistance, but the voltage dropped across each resistor is determined by the current through it. SO the V1 might have the same 30k between it and the power source, but the intervening stages all draw their current through the middle resistors. SO that is what will determine the ultimate voltage drop across the whole 30k.

I'd agree that if the B+ for your stage is XXX volts, then it doesn;t much matter how it got there.

Thanks Enzo, thats exactly what i wanted to know.
