I'm repairing an FT-1000 (no suffix). The power amp driver stage (Q7002/3,
MRF486's) failed, taking a few resistors with it.

1. Does anyone have a cheap source for the MRF486's? (Yaesu wants around
$114 for the pair, and RF Parts wants $89.)

2. Does anyone know the bias current for this stage, i.e. the voltage drop
across R7014? I don't have a service manual, only the schematic.

TIA.
