Is it normal for the Sprout100 exterior to be too hot to the touch (especially if it’s just on with no audio playing or it’s after 2-6 hours of operation)? My other amps don’t get hot like this and I have the Sprout100 placed in an open spot with good air circulation. ---

My Sprout100 was never more than warm to the touch. I think you may have a problem. ---

Same here. Warm to the touch and it has been running 24/7 for a year or more. ---

Mine is on 24/7 and is warm but nowhere near hot. Time to call PSA CS. ---

Like others have said, it gets warm but should absolutely not burn you. I think you should give our guys a call. I’m not sure the expected operation temp, but it shouldn’t be too hot to touch. ---

yeah, being that it’s class-D, and no tubes, it should generate very little heat. ---

My Sprout does get warm at times. I’m wondering how much ventilation is needed. Any advice on how I have it stored? I thought an inch clearance at top might be enough but not sure. The sides are clear but it does get very warm. ![IMG_20230730_153640_580](https://us1.discourse-cdn.com/flex015/uploads/psaudio/original/3X/0/f/0f21bcc7f7514d36379082dc3d0a548a7628883c.jpeg) ---

They do get warm when running. I have one in the machine shop that has been on 24/7 for a few years now and is still working fine FYI. ---

Thanks for taking time to respond Paul and Baldy. A bit of paranoia was creeping in as I didn’t want to cause damage to the sprout. ---

Isn’t it Class D? If so, just warm should be expected.
