I have seq v4 with wilba CS working fine.
I add the line driver + aout ng modules connected by scheme for seq users from www.ucapps.de/mbhp_line_driver.html (j8/9 of core to j1 cs; j2 to j2 transmiter; j19 of core to j19 transmiter etc.)
and in result have crazy seq.(screenshot) and MC3486, MC3487 seems warm.
Check for shorts on line driver pcbs- all fine. Pinout seems normal. Some result without any connection fron transmiter. AOUT seems work fine.
Tell me please where to look for error. Thank you.
