i bought the newest driver board for my 70. now...ive built kits and can solder nice but modifications without specific instructions i`m weak at. question is what do i do with wires 11&14 from the old board. and also there were two resistors on the old board soldered to ground at the rca jacks. do i just cut and omit this ground? and does this board need a ground? thanks for your help. i`m allmost there.

Hi Jeff,

Yes, 11 & 14 are removed, as are the preamp wires at 3 & 18. Toss the old resistors from the RCA jack, along with any jumpers and that stereo switch hookup. Just have two short wires running from the RCA jacks' input and ground to J7 & J8 and J17 & J10, respectively. Noise floor tests that I did a few weeks ago were excellent!
