have exerted a profound influence over the audio industry across time. How many thousands of music lovers have (and continue to) enjoy a wide range of reasonably priced Dynaco and Hafler products? As for me, I owned the PAS-3x, PAT-5, FM-5, and ST-120 in my early years. I built the middle two from kits.Frank Van Alstine was the first of many to recognize the underlying potential of many Dyna and Hafler products. He took them to a new level of performance using higher quality parts and stiffer power supplies beyond the scope of Hafler's intended cost targets. It was one of FVA's enhanced PAT-5s that replaced my Citation 11 in '76 or so. Where Dyna used the cheap LM301 opamps, he replaced them with LF356 FETs. All of the (noisy) 5% carbon film resistors were replaced with Dale 1% metal films. Similar upgrades were made to the 'lytics in the signal path. All solid engineering moves. It was more dynamic and cleaner than the otherwise good Eleven.
I used it until '81 when I moved to the next level of performance with an Audio Research SP-6C. I use a hybrid SP-9 MKIII today. While my system's sonic capabilities have progressed beyond those days, I will always have fond memories of Hafler's products. As for Frank, he continues to offer upgrades to those many Hafler children still in the field.
