Decade amplifer of conventional phototransistor pyrometer control was modifed by removing output transformer and load inductor, lo give additional feed-back at low frequencies. Bootstrap emitter. follower stage was added as output buffer to improve circuit stability. Used for measuring high rocket surface temperatures.-S. A. Edler, Designing Phototransistor Pyrometers With and Without Feedback, Electronics, 34:49, p 56-60.
