Here is a cross reference index for many Zenith OEM part numbers. I have available for sale many of the original Zenith transistor types. For those who prefer original transistors to a general replacement type please visit my parts page. Also, please visit the cross-reference page for some replacement transistors for the Zenith R7000-2 Transoceanic radio.

Also, additional cross reference information can found at the NTE Website. This site lists a number of higher P/N Zenith transistors not listed on this page. For Heahkit enthusiasts, I have found a nice Heathkit semiconductor cross reference page at this Website.
