What is this electronic component?
During one of my part harvests I came across a rather odd component. It looked like a black rectangle with steel pegs protruding from one of its sides. The part's etchings are a white dotted line followed by what appears to be a mitsubishi symbol followed by the text "E 27k", an ohm symbol, then " 9428". I found this part on the board of what I believe to have been part of a tape recording machine. Attached is a picture of the component. If anyone can identify the part I would be eternally grateful.
