carbon film resistors are not as good as wire wound? Just curious...perhaps because they could burn out fast? I have 100k wire wound and 1 meg CF.

Wire wound resistors do not resist.....sounds weird but they act as a coil, ergo they are useless.
A coil has an impedance, such is not the same as resistance, sadly both expressed in Ohm.

AC Ohm is quite different from DC Ohm, that is the problem.
