Parasound halo JC2 what a joke

Had a jc2 power button fail because the glue that mounted it on fell off ! I guess they glue the input and power buttons on to the face plate . So I sent it out to get fixed , $175.00 with shipping and the repair shop put a small scratch in the face plate . The repair shop is like that must have been there I didn't do it . I call parasound and talked to the owner he said he would talk to the repair shop and call me back . 2 weeks later I called him back and he thinks i'm pulling a fast one on him or something ! If I dinged the front I would have said put a new 1 on . I drive a new caddy I think I can afford it ass$#@# .

Don't give them a bad rap.

90 degrees centigrade or farenheit? For equipment that is meant to be on all of the time, 90 degrees farenheit is actually pretty cool running. I am sure that the power supply on my Naim NDS server runs hotter than that, and it is intended to be on all of the time. Back when I ran a Levinson No. 32 preamp, the main box was probably around that temperature and the power supply ran much hotter than 90 degrees farenheit; if the unit was left off, it would take forever to get back to optimal performance.

All I see over at AA is YOUR post that's identical to the one you posted here.

Okay, I just read the JC2 manual and found the Ventilation Requirements section which is included below:

Because the JC 2 is a high current class A design it is always slightly warm to the touch, even when in standby. To reduce the chance of your JC 2 overheating please follow these guidelines:
• Install your JC 2 away from heat sources such as heating ducts, radiators, or heat-producing components.
• Always position the JC 2 horizontally.
• We recommend that you do not place the JC 2 above a power amplifier.
• Do not install the JC 2 in an unventilated equipment cabinet or compartment. Pockets of stagnant hot air can build up even in cabinets with open front and back sides. A ventilation fan such as the Parasound Zbreeze is highly recommended to prevent “hot spots” in confined spaces.

Okay, it says it runs "slightly" warm. my guess is Maggy44 has his directly above his amps or next to a baseboard heater of some kind. Perhaps he measured it before the cabinet interior had cooled down. Whatever.

I agree with Larryi. The JC2 is specified as consuming 25 watts of AC power in standby, and 30 watts when turned on. For a preamp of its size and weight (24 pounds), a consumption of 25 watts seems to me to be perfectly consistent with a temperature rise on parts of its housing of perhaps 20 degrees or so above room ambient temperature. In other words, to about 90 degrees F.

I don't see that as being of any significance, as long as a modicum of common sense is exercised with respect to placement and ventilation provisions.
