Hi Gene, I looked at that before, to try to work out a set of values to buy from typical Chinese sellers - see the first diagram. I went for 5 Ohm at R8 and the diagram shows R7 staying at 33 Ohm. Theres no tonal consequence (less than 0.1db at any frequency) but it shifts the attenuation down by about 0.15db. When you step through the range, then the series of increments available at each step, intended each to be -3.5db, then vary from about -3.3db to -3.7db. With the specced values the range is about -3.5 to -3.6 db, so a tad more consistent.
If you change R7 from 33 to 30, with R8 at 5, then its back to virtually the same as specced.
Thanks for that info. R7=30Ω & R8=5Ω. Makes for "Mo Betta" ordering, availability, etc!
