早期的金嗓子、麦景图等功放，其电源尾座是两针式的，，与现在的三芯电源插互不兼容，，所以，唯有改辕易辙~~~~~~~~~~

所更换的电源座，一定要使用日制规格的，这样安装时，就只要调个个就得了~~非常的方便快捷，。。连一个螺丝孔都不用重开的，，一切照旧~~~~~[s:6] [s:6] [s:6]

看图——这种早期的放大器。其喇叭接线端子，现在看来也算是很特别的，不用改了，这会很麻烦的——现在有了一种“即得是”喇叭端子转换接插头..............对麦景图、金嗓子功放可谓是“巧夺天工”的美事~~~~~~

[size=-1]Description [size=-1] Monophonic power amplifier which allowed no compromise but was completed over long time aiming at improvement in much more quality of playback music. By considering it as monophonic power amplifier, while suppressing the mutual intervention between right-and-left channels, weight and size are limited to the range which can be treated alone. Based on the active device which was excellent in the high frequency characteristic, circuit composition constitutes all the magnification stages from a symmetrical type push pull, and has realized the outstanding standup characteristic, linearity, and stability by giving a little NFB. thereby -- TIM -- also setting at the time of full power, while preventing distorted generating -- low -- the distorted output has been obtained. Moreover, in order to realize sound quality with few colorations, the capacitor in a NFB loop is removed and it has direct-current amplifier composition. Energy as big as 152J is gained by impressing the high voltage to a large-sized transformer and the filter capacitor of 22,000 micro Fx2 at a power-source part (P-300 type is 120J). Thereby, the low-pass output characteristic is improved sharply. The logarithm compression type which can carry out the continuation Direct reading of 300W from 3mW is adopted as a power output meter. This meter can change both peak directions and volume directions with a switch. The Subsonic Filter is carried in order to cut an unnecessary super-low-pass noise. As volume control, adjustment of a 1dB step is possible to -20dB, and less than it carries 25 contact rotary switch of -23dB, -26dB, -30dB, and -infinity. Also in consideration of a studio monitor or the use as an object for PA of a hole, it is considered as 19 type standard rack-mounted form, and the canon input is also prepared. For the reason when setting to the place where the heat dissipation effect is very bad, or carrying out continuous use by the Oide power for a long period of time, the optional fan for airs cooling with blower can attach.
