Default This has me puzzled (resistor change)

Very high value film resistors are made with some composition sprayed on a

That can add inductance, and the higher the resistance value they
are aiming for, the more inductance.


** Absolute CRAP !!!!

Where does this ****e come from ??

ONLY with *low value* resistors can the TINY inducatance created by spiralling become significant and then only at RF frequencies.


In tube circuits, it is not unusual to
have megohm resistors, so I can see how this could be a problem.


** Huh ????

Jumps straight from the rediculous to the absurd.

Go away fool.
