Old RCA semiconductors

Sep 25, 2007 2 Replies

I was cleaning up the shop and I found a box with the following RCA parts:



146303, Comm Thyristor
146302, Trace Thyristor
142681, SCR
145784, Thyristor
145783, Thyristor
142689, Transistor These I believe were all for 1970's or early 80's sets which we'll never see again, however they are all brand new and are viable semiconductors. Is there any way to find out what the original specs for these were so that perhaps they could be cataloged and possibly used in a different application requiring that type of device? In addition to these RCA parts, I have another box containing Zenith System Three semiconductors too. I would hate to just simply throw all this stuff out. Thanks, Lenny Stein, Barlen Electronics.

Look up the part numbers in the NTE data book (or on their web site) and see which NTE devices they cross to. Get the specs for those NTE devices and you have a pretty good idea of what you have in your box.

Why not donate them to the Early TV museum, along with he Zenith Safety caps? They will need thm, some day, and there won't be any beacuse so few shops keep obsolete parts.
