"Well this was winter so we put some snow in a plastic bag in between the heat sinks."Many, if not most, of instruction manuals start with "do not expose to moisture/water" or some variation of thereof. Not that it should be mentioned, but apparently.......well, apparently not everyone reads instructions most have learned early in life. First grade of elementary school early. While at that, do not use hair dryer in the bathtub. |
"Did I mention it was the old Phase Linear with the huge heat sink fins?...........Bob thought it was pretty clever."Bob cut his first grade elementary school classes and did not read the warning on page 3 of Phase Linear amplifier instruction manual. https://bradshirakawa2.files.wordpress.com/2013/06/phase-linear-400-ii-instruction-manual.pdf NOTE: page 3 is the page between page 2 and page 4 (it is not numbered like 2 and 4) |
@tomavodka: It’s very normal for Krell amps and most class A biased amps to become very warm-some even hot to the touch. Be sure not to impede the air flow around them, thus no stacking other components on top, or placing them inside cabinets etc. Common sense stuff. Remember-a class A biased amp is always “wide open” when turned on. I have stated this comparison many times. They’re like a hot fuel dragster sitting at the line waiting for the the green light.

At full Blast, my amps run slightly warm. I attribute it to the huge power supplies that allow the outputs to coast as they alow the electricity through, rather than working hard to extract it from a small power supply. The amps use very little bias, because it is not necessary, and causes heat to be produced. Since the amps a in the next room, I did use a small fan on a Bryston for a while. One interesting design for an amp is the Audire Monarch. It is a tower lined with many output transistors, and has an open bottom to let air rise for cooling out the highly vented top. The design reminds me of the old GE tube amp my family's movie theater used in the 1950's, but could have been even older.. It was 100 watts, about 5 inches thick, at least a foot and a half wide, and about two feet tall. All visible surfaces were totally perforated. Some audiophiles like to open the tops of their amps. This did help my Bryston run cooler. |
