许多发烧友都有见异思迁的特点,愈是新颖的电路,愈是有兴趣,有一试方快的感觉。笔者偶然看到《一种不用电源变压器的扩音机——高淳放大器》一书,于是按书中介绍,自制不用电源变压器,直接用市电整流滤波,用6N2、6P1制作单管甲类电子管功放。这样制成的电子管功放,当接驳调谐器、录像机时都能正常工作,但在接驳电视机(熊猫3608型)的开机瞬间,电视机烧坏了,声像全无,检修时发现电视机的高频头、二
Many audiophiles have their own characteristics, the more novel circuits, the more interested, have a quick feeling test. Occasionally I saw “a power amplifier amplifiers - Gaochun amplifier,” a book, so the book introduced, self-made without power transformers, direct rectifier with the mains filter, single tube with 6N2, 6P1 production of tube amp. This made of the tube amplifier, when connected to the tuner, VCR can work properly, but the connection TV (Panda 3608 type) boot moment, the TV burned out, no sound, repair found TV Machine tuner, two
