I have two 7061's, and yes, they run quite hot. I do leave mine on for months at a time, though, and they run just fine. Don't touch that little metal box inside, though. It gets VERY hot. :) Amusing thing is that it's not an oven, it's just a shield around some noisy 74Sxxx chips. Regardless of how hot they seem to run, they were designed for continuous use. I figure if they've lasted 30 years, they'll probably keep going. The 7081 runs considerably cooler. On 08/05/2011 08:00 AM, volt-nuts-request@febo.com wrote: > I have the 7061.

Thanks, that makes me feel better. Yep, I found out that metal box gets very hot. Glad to hear it is normal. I think 33 degrees in my lab and the meter standing 1 cm under a wooden shelf was not optimal. I now have it on a cooler place and I think I place a heatsink above the transformer on the outer cabinet o It can lse its heat better. The trasformer toutches the top lid and If I look at the shape it is done by cooling purpose , so a heatsink on that place will help I think. I think most labs are airconditioned and a lot cooler.

What is the power consumption of the 7061, anyone know? At 10:40 AM 8/5/2011, Fred Schneider wrote: >Thanks, that makes me feel better. >Yep, I found out that metal box gets very hot.
