Please sign your name. It's so much more personal than "Dear VRM SYSTEMS
& GADGETS."
It is my opinion that low-value resistors, less than 1.0 ohm, are
critical and should be replaced by the same value. The 0.6 ohm resistor
will dissipate more power and is more likely to fail.
The 0.1 ohm resistor is not easy to find. Few suppliers I know of carry
it. I use the Sony 1-202-933-61/11. From Sony, they cost close to $3.00
each. Places like Electro Sound or Suburban have them on sale regularly.
I have paid as little as $0.69 each for them. May still seem like a lot
for a resistor, but even three dollars is better than a recall.
