1) 남이 안하는/못하는 Plate 특성표 발표 동작점 추천한 것 (중국제는 자신이 없어서?)
2) TEST/추천 - Lundahl OPT 를 사용했다는 것 --OPT 구조가 R-core OPT 하고 가장 가깝다는 사실

Choice of output transformer impedance: For each working point, a wide range of primary impedance is possible. When using a transformer of another value, you can estimate the output power and distortion by averaging between two rows of this table. Example: 450V, 60mA. Use of Lundahl LL1679-70mA (4k5 type). This will give you appr. 11.5 Watt @ 27dB 2nd harmonics. (28dB distance of signal to 2nd harmonics. |
