    As title states - just how hot do these get under normal use?
    Historically used to Yamaha's that run cool.
    There are some excellent bargain pricies on the TX-SR805/875 and tempted but the question of heat and possible failure putting me off
    Any posts re owners and experience with these models appreciated
    Many Thanks

    mine gets quite hot but its never missed a beat. Looking round the forums Ive not seen a single post of one failing from over heat. Simply put they are designed to run hot, and do just fine. You can buy a 12v triggered fan if you really want.

    On the OSD you can get its temp up, I think from memory ive seen 67 internal temp displayed.

    mine has ample ventilation so is fine. Does get fairly hot though.

    Dont let the horror stories put you off the 875, this is an amazing amp at this price. Also should come with a 3 year warranty anyway.

    Had mine 9 months now and it hasnt given me any trouble, makesure you get one with new firmware.

    In my experience, when listening at lowish/moderate volumes, the amp used to run hot.

    I found that this was mainly caused by the REON video processing circuitry at the back/RH top side of the amp. If the video processing was not used (set video source to "through") the amp runs as cool as any other I've owned.

    As I don't like to run things hot, I used a couple of 120cm PC case fans on top of the case to draw the warm air through and prevent a heat build up - that worked a treat.

    As per the other replies; it's not as bad as some say providing it has room to breath & remember it is designed to work in places with really hot climates & they do give a 3 year guarantee, so don't worry :)

    This was something that originally worried me when I was considering the 906. However, they are designed this way, and even with my Reon processor on, my amp will play at very high levels for hours on end. There is noticeable heat output but this does not affect the performance at all.
