D76 Inrush current limiter thermistor?

bwaslo · 10th July 2011, 08:58 PM

I have an Audio Research D76 amplifier with a blown inrush current limiter PTC thermistor TH-1, AR part number 47000. I've found schematics all over the internet, but no identifying parts lists. It's on the primary side of the power transformer, in series with a 5A SB fuse.

Does anyone have a good idea of what the ratings would be on this thermistor? Thanks.

The D-76 is fused for 5 amps -- so the KC006L (rated for 5 A continuous) will probably work. I don't know whether this is the device spec'd by AR, however.
