[Amps] Advanced Power Technologies ARF1505

[Joe Subich, W4TV]

Mike, 

Contact Dick Frey, K4XU.  Dick is Manager of RF Products at APT. 

I believe the ARF1505 is the subject of an article in QEX (July?), 
is being used in a Tokyo High Power Labs amplifier and "may" 
be available in a package similar to those from CCI (board, etc.) 
at some point. 

Dick referred to the transistor as "the modern 3-500Z"
