    I know there is some mojo talked around using carbon comp resistors in circuits. I recently got a couple old radio tube units from the 50’s. The resistors are all solid carbon body-tip-spot types. There are several on the mica domino caps in there also which would work in a tone stack. I’m getting ready to build a 5F6A chassis to put in an empty RI cab I have.

    If these parts test out good, is there any issues with trying them out or should I just stay with new stock?

    Thanks, Joey

    I dont see any positive other than saving a few pennies with using ancient resistors.

    Yeah, not concerned about cost, just wondering if there is any “mojo” linked to these things.

    Wait, let me get some popcorn before this thread unfolds any further -- you've just opened the Pandora's Box...
    To start things off, IMHO no mojo there unless you like noise...

    Yeah, the general consensus I've heard around the DIY scene is that the only "mojo" to be had in carbon comp resistors is a bit of extra hiss that somehow translates to "vintage" which subsequently translates to "better" or something.

    That said, I don't think there's any harm in using those old resistors, the noise isn't bad unless you're doing a high-gain circuit, it'll keep them out of the landfill if nothing else, and the vintage look isn't a bad one...

    If mojo=noise then yes

    If you think they look cool, then use them! Plenty of other folk pay way more for stuff for exactly that reason, because their eyes (and wallets) tell them it sounds better. And in your case, you're not paying more for the Mojo.

    Thanks guys, I will play around with them then and see what I think.
