My service manual trace side pic and schematic agree. Rk-1 150 ohm 2 watt metal film to collector of a 2SC1419. My board has 2 330 ohm 2W MF's in paraelle. The board is factory drilled and both resistors have factory Z bends in the leads. Both of the 330 ohm resistors got pretty warm traces and pads ok. Did not find shorted 2SC1419? Ideas or maybe somebody has a different pic or schematic of this board.

Thanks dave

Schematic here shows two 330 ohm resistors.

Thank You Dave was using info from manualslib. On pages #27 & #35 of theirs shows a single 150 ohm 2W MF. Well theres my confusion. I will download a manual from them! Maybe a running change or revision from Kenwood. Who would know,I relied on theirs. Thanks again.
