Very well taken care of as can be seen in the pictures; 

This is a steal for an amateur radio or electronics tech's bench.  

These transformers are invaluable, if not mandatory, for working on old, antique AC/DC sets, and vintage radios with leaky capacitors in the power supply.  

Antique radio restorers please take note.

Overview

Isolation transformers are power transformers for isolating equipment from direct connection to the power line. They are offered in a variety of voltage and case types. 

TRIAD isolation transformers are also offered in a hospital type (designated with an MD suffix), which are designed and constructed to meet the low leakage current requirements for today's medical equipment. 

The transformers are constructed with nonconcentrically precision-wound coils. 

The primary and secondary are precision wound on separate arbors, then assembled on a laminate core side by side separated by insulation. 

This prevents electrical connection, under normal or overload conditions, between the primary and secondary windings. 

These hospital type units are offered with a resettable circuit breaker, providing protection from overload and short circuit conditions. G suffix denotes ground.
