While I do not have the older 801 schematic       here (the one I have has no 0.47 ohm resistor), it's pretty       like that enough power through that resistor to blow it up       happened at the same time as a LOT more power through       something else.              Another possibility is that when a driver went, the topology       of the network was now changed sufficiently that MUCH more       power than normal went through taht resistor, and it failed       AFTER some other component failed.              But while, if everything else in the speaker is okay, upgrading       the power on that resistor will have no effect on the sound of       the speaker, because something else may be broken, replacing       the defective resistor with ANY wattage may well not fix the       speaker.              --       +--------------------------------+       + Dick Pierce |       + Professional Audio Development |       +--------------------------------+              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
