JRotten 2 Posted May 9, 2019 Share Posted May 9, 2019 One wire is for signal and is not used. Yes the fan board taps the 50V supply but the fan does not see 50V. R2 is changed to 65 ohms (parallel 130 ohms) to attenuate quiet mode further. 1 Quote Link to post Share on other sites
kingman 5 Posted May 9, 2019 Share Posted May 9, 2019 If my memory serves me Zumbini used to have some of these. He may still have one for sale. Until forum is up no way to contact unless someone has his personal email. 1 Quote Link to post Share on other sites
JRotten 2 Posted May 9, 2019 Share Posted May 9, 2019 Tim, when you say PT 1.5 do you mean PM-1.5? This fan mod was designed for the single fan PM-1.5 pictured. The resistance value for R2 was measured for the PM-1.5 amplifier and the fan shown. A belt sander was used to bevel the bottom edge as well as trim 1/32" from top and bottom of the fan. When mounted properly, it moves just as much air as the original mainly because it has a built in shroud and OE did not. 1 Quote Link to post Share on other sites

You can replace with an aftermarket or try the link provided to fish for a replacement on the Carversite forum. Sometimes cleaning and lubrication are all that is needed to alleviate fan noise.
