Tech: Rowe R-83
Working on a Rowe r-83 the right channel output transistors are out.
MJE 6041 MJE 6044 Crossed with NTE and they are obselete. Anyone know of different transistors that will work? Thanks in advance Todd |

You may get a more complete answer on one of the sci.repair NGs, but here
are a couple of hints. I think those were Motorola Darlington transistors in a proprietary package. Darlingtons have fallen out of favor, but are simple combinations of two transistors to increase gain in one package. We used to make our own out of a small signal transistor and a power transistor. See any elementary transistor text for details. Second, many of the products in that package were also available in more common (like TO-3) packages. Unfortunately, at this juncture, you need a tech who is up with both current and old technology to develop a list of possible substitutes. I cannot find those original numbers in my very old Motorola manual, but they may show up somewhere else on the 'net. Once you find the specs on those devices, then it is a matter of using device selection charts to find an electrically equivalent device, and then figure out how to accommodate the different package. -- Crazy George Remove N O and S P A M imbedded in return address "TMcderm653" wrote in message ...
