    This amp is getting VERY hot when used for 30 or more minutes. There is no fan.. is this correct? Is it supposed to get hot?

    Well I don't own a workingmans 4004, nor have I played one, but I don't think any amp should get really hot after only 30 mins of playing, unless you have everything maxed out at 10 on it.

    See if you can take it to a tech or the person/store you got it from, if all else fails you'd probably have to send it to SWR or something.

    But first find a good amp tech or take it back.

    Well, that shouldn't happen. I've used one for 2+ hours and didn't have a problem.

    If you are taking the amp below it's recommended ohm load it will heat up quickly. What are you using for cabs?
  6. SWR amps run hot. You didn't mention it, and I couldn't find your cabinet of choice in your profile (ahem), but I'll go out on a limb and bet that you're running a 4 ohm cabinet. If this si the case, it's normal. My head (WM 160) is on fire when pushing a 4 ohm cabinet to practice levels. It usually takes less that 5 minutes to cool down to when it can be touched again.

    swr amps use their outer shell as a heatsink, it's supposed to happen.

    Most SWR amps get very hot, they radiate their heat through the chassis. Don't know if the Workingman's series is designed the same way.
