Not a fan?
All I've got to hand is a little bag of 100 ohm metal film resistors. I'm guessing they're rated for 0.25 W.
If I run a few of these in series for each signal wire should I expect them to fail?
Also, if I use coupling capacitors as well, can I expect the output voltages to quarter? Would you recommend using both the coupling capacitors and a ground loop isolator?
