I have looked at the datasheets and wanted a 2nd opinion not a smart

I wasn't just making a smart remark. It seems that you want someone
else to do all the work for you. The data on both types would have
immediately told you the NTE device was not the best choice.

It is a logical step that when considering a substitution of
components you first of all find the data on what you have and then
what you want to replace it with. If you had studied the data sheets
you would see that the package types are vastly different for a start.
Next thing is that the NTE is a darlington type with bias resistor and
it is rated at 28A whereas the BU406D is only 7A.

The NTE package type will make it hard to fit in the existing holes
plus the fact that it will cost over $20 as against maybe $1 or so for
the BU or other equivalent device.

If you had done some searching in the UK using Google you would have
found several possible sources for the BU406, 407 or 408D.

eg. http://www.dialelec.com/302.html

There are other possible sources I will include in another post.
