I received a note from K4XU the other evening ...
The Tokyo High Power article was missing from the July QEX -
no reason why it did not appear. Both THP and Dick were
surprised as they had been told it would appear in July.
The THP design uses the ARF1500 - not the ARF1505 in push-pull.
The ARF1500 provides a much more constant Zout which simplifies
the output transformer and the 125 volt operation simplifies
power supply design.
Note there is an error in the Product Matrix on the Advanced Power
web site: the ARF1500 and ARF1501 are also specified for class A
- class E service (the product matrix says C-E).
73,
... Joe, W4TV
