Recommended Posts

I have a PT 1.5 that needs a fan motor no one knows where to get one called carver in detroit they said $350 + shipping. I only paid $150 and replaces the caps myself for $60. Anyone have a fan motor?

How do you wire it the amp only has two wires? the power supply to the fan says 50 volt this is only 24 volt?

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.

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.

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.

sorry it was a pm 1.5 and the place said it was authorised service center for carver, i called them they said the had a box of them but you would have to send amp in for a total refresh they would not just sell me a fan motor.

sweet! I am about to buy a pm-900 maybe...the only thing stopping me is that fan..they are loud when old .

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.
