need help with a resistor value

[Anti-Hero]

Im repairing the cathode resistor in a crate v100h amp, but im having a hard time finding a 3watt 10 ohms resistor to put in there, I have looked online and all I can find are the non-inductive white ceramic ones at 5 watts.

will i have any problems running 2 x 2 watt 5 ohms in series?

Thank you

No problem at all. You will also have no problem using the 5 watt. In fact I would recomend the 5 watt. The circuit doesn't care and it isn't to big physically. The worst thing that can happen is that it would be more reliable.

really?, Im a still new at this, but i was under the impression that you couldnt use those

Why? As long as it is the right value and can handle the current the amp doesn't care.

i went out to the store and bought a couple 10 ohms 5 watt resistors, and none of them test anywhere near 10 ohms

no my day

some multimeters seem to have problems in the very low Ohm range. I have a Fluke that I use for low impedance testing.

unfortunatly it snaps to 10 ohms on the other tubes, this reads 00.3

Are you measuring tubes or resistors? Are the other ones in circuit or out? If the others are out of circuit and measuring 10 ohms we can assume your meter is ok. If your meter is ok and the new ones don't measure what their value is supposed to be then they are bad.

the other 3 measure 10 on the dot, meters fine, someone at the store must have labeled them wrong

[g1]

I guess they were in a bag with the value marked on the bag? The body of the resistors themselves should be marked with their correct value.

Change the battery in your meter. I would lift one lead of the in circuit resistors and measure them out of circuit just to make sure. If they still measure 10 ohms, it sounds like you may have bought .33 ohm 5 watt ceramics. They are common as dirt for emmiter resistors in big transistor amps and stores carry morr of them. I've seen this happen before.
