LOL!! - when do you find time to play , Man !!! this is fun...
I'm sticking with 500ohm for now but I'm rooting through my stuff pulling out all the values of cement Power resistors I can find - this is getting like an obsession and the amp isnt off the bench yet.
cheers

Well it's not to hard to get me away from doing my taxes today so back to the A/B'ing 250 Ohm vs 500 Ohm. With the volume of amp and guitar on high I record a 7 volt drop at B+2 with both resistor values when hitting a hard bar chord. Perhaps that is not a technically correct way to measure "sag". Lacking a background in electronics I assumed "sag" was a term to describe a voltage drop and its time to return to normal and would be perceived or experienced by a blooming or swelling of note volume after a hard attack due to the delay in the voltage returning to its steady state at rest. My perception previously was that phenomenon occurred slightly more using the 250 Ohm resistor. I don't have the right equipment to test the length of time it required for the voltage to return its initial value. That however might yield a difference between the two value resistors.
I never claimed to "know", just shared my opinion regarding my amp, fwiw. In the interest of education, any of you more technically inclined types care to proffer a definition of "sag" from a technical point as well as how one might experience "sag" playing. I hate to think of the liability and embarassment of people falling off their chairs laughing in the workplace due to my ignorance.
