Thanks to all of you for the replies. The first interest is to build and
test a 300 watt input and output transformer pair.
The reason I chose #43 to discuss was it was mentioned in at least one
of the Motorola 2 to 30 MHz amplifier app notes. Should #61 be used for
this purpose? Should the input and output use the same material?
