Lionel 1665 Engine

I have a #1665 PRR switcher. For some reason it stopped smoking. It looked like it had a different kind of heater element. Does anyone now if it takes the old style of heater element or this diode looking one?

Hello PhiladlephiaKnight!

It uses the diode version & Jeff Kane should have them in stock at: www.ttender.com. Take Care.
