service manual or schematic for pt1250 pt1800 pt2400

Hi,

I got a PT2400 but its fan is quite loud for home audio listening. Since the PT2400 is very similar to the TFM75 which doesn't need a fan for cooling, I'm hoping that it will be ok to disable the fan for home use. Have anyone tried this or have any relating info?

Thanks.

x2. i have some thermal switches that i am going to use so the fan will indded work if it gets hotter than not.

vette, both the 2400 and the 75 have fans. FYI
