Metal Film??

Are these metal film? They're 20ohm, 1%, made by Dale. I've never seen these type before. I definately have one of the most awsomely useless collection of resistor values on the planet.

Yes they are.

Yes they are.

High Dollar,Metal film for sure Fretwire, they come in all kinds a color's, but I've yet to get anybody to tell me if that means anything or not.

Thanks guys. Sorry about the poor lighting, they're dark tan/light brown.

What exactly are those? (part series/type/numbers) do you have a Dale part number?

I've been looking for those types, I want to use some in an amp circuit buy can't find them, exactly.

(don't happen to have a Mouser numvber do ya?)

This is what they have printed on them:

Dale
C55-39
20ohm
1% TI
0018

I don't know if they'd be worth the bother for amps when you can get regular 1% metal film easy. No Mouser #'s, I got them in bag of assorted values.

i wonder what the power rating on those is...

Looks like they are special purpose flame proof.

Edit: on second thought it looks like these: :?:

Metal Films are readily available in many resistances from digikey as well --> www.digi-key.com

I buy a lot of stuff from them.

Yeah I can get 1% metal film all over the place, but I was looking for those particular ones for a friend's amp, he saw them used in Mojo amps (or some amp) and wanted them in his mod'ed Marshall.

Mouser does have them. Look under Vishay/Dale CMF series metal film resistors. Use the CMF-55 number as a starting point.

...ROTFL...

One day in the power supply design group, our secretary comes marching into the lab and says in all seriousness "Hey, guys - what color is a capacitor?"

...ROTFL...

Tell your friend that it's not the brand of resistor or the color that counts. If he refuses to believe you, then tell him you have some special wiring that Jimi used in his Marshalls that makes the sound much more (insert anything he falls for here) and that you'll sell him some for $85 a foot.
