thanks for the tips Sonoma!
i generally use the "x10" formula when extending the audio bandwidth.
if i want to increase it, and the stock part is .047, i go with .47 etc...
seems to work pretty well.
i will say this to anyone who does this type of modding; ALWAYS parallel the old part with the new value and check the sound before moving on to the next cap. (obviously when trying to decrease the value, you have to unsolder one side of the old part, pull it up out of the hole, and temporarily solder the new value in place on the solder side of the board)
each chassis responds differently to these types of mods, and you absolutely need to know which part makes what difference.
for example, if you were to just do the "MMM" hi fi receive mod as its stated on his site without experimenting; you may find that the receive is too muddy for your tastes.
dont forget that many people have different hearing ranges.
I like the MMM mod, but i dont remove C185 and i add a variable tone control.
that is just how "I" like it. YMMV
