[Amps] Looking for article from Ham Radio Magazine June, July, Aug 1979

[Bob and Bettina Groh]

Looking for a copy of a 3-part article by W6SAI entitled 'Linear Amplifier 
Design'. It was published in Ham Radio Magazine, June 1979 (page 12), July 1979 
(page 34) and August 1979 (page 58). I got rid of all my back copies many years 
ago!
