For your consideration, and from my own personal collection, is a low voltage selenium rectifier for the Marantz model 7 tube preamplifier.

This is an original, not a reproduction, Made in USA by International Rectifier in El Segundo, California. International Rectifier was the original supplier of rectifiers for the Marantz Company in Long Island City, New York. 

This rectifier is an exact replacement, manufactured in the 1960's. It has been tested and found to be working correctly.

 Don't settle for imitations, preserve the collectability and sound quality of your classic Marantz tube preamp!

 Thanks for looking and don't forget to check my other listings for more Marantz parts including a very rare Clarostat dual 500K volume control.
