I wish it would be true and I would be busy to build my loudspeakers. Unfortunately it is a lot of work and I did not have even time to look at my site. The r22, the power resistor is not necessary the one which mitigate voltage in your tube. Certainly it might but it is not good idea to adjust voltage to transferring it into heat. The main objective of r22 is to decouple one stage of filtration from another. The input LC filter does what it does and the capacitor across as a second filtration stage decoupled by a resistor. If it gets overheat then you drive too high current over it. You drive too much current only if the impedance of your load is too low or if your supply voltage too high. I would not give up the power rating of that resistor but I would rather recommend to find the reason what make current over it too high
