PEC = Packaged Electronic Circuit. An early implementation of circuit integration/miniaturization. Usually contains ceramic caps and/or carbon film resistors on a ceramic substrate. PECs were specialized designs to accomplish a specific function so there were scores of them produced, all different. Typically used where cost or space savings was important...like AA5 AM radio. The one in the attached pic is the low filter module for a Mac MX110 that uses other PECs for hi filter and tone controls. This one ~ 1"x3/4"x3/32"and contains 3 caps and 4 resistors. Usually assoc with tube equipment but also in early SS products. Visually IDed by appearance. The spawn of satan from an audiophile perspective. Others may disagree.

Edit: Before the Internet correctness police strike, I've also seen PEC = Printed Electronic Circuit.
