hello group, i am looking for pa7ta style 432 and 144 mhz amplifier design. i have found many photos but no nice drawings. i had built a yu1aw stripline for a gs31 but my nos tube is bad. so there it sets. i do have several gs35 tubes so i figured i would build around one of them unless i can find a cheap gs31 without cooler.
