is it really required to use carbon comp for grid stoppers?

[poobah]

So it's dental mirrors you're after eh?

No, it certainly does not mean that they are doing anything "wrong". This is yet another bit of BS folk wisdom. Back in the "good ol' days", everyone used carbom comp resistors because that was the only choice for low wattage resistors. These days, we have the better alternative: metal film. Metal film resistors are a good deal quieter than carbon comp, and therefore best to use in low level stages especially.

Oh Great,

I finally replaced/retired my entire inventory resistor storage bins of 1/4w carbon comps with 1W carbon films now I have to switch to metal films??


Make up my mind!!

I have to switch to metal films?? Make up my mind!!

Yes and no: Yes, you have to switch (avoiding the fire hazard too, by the way); and NO, I can't make up your mind.

Just kidding, YMMV 😀

Speaking of fire hazard, being students we used metal film resistors when were out of matches...
