Berning-EA2101-pwr-sch维修电路原理图Tag内容描述：
1、 For units set up for 240 volts, a 50 ohm10W resistor is inserted in line with the incoming mains power. CAUTION: Danger。
2、 The 6LF6 output tubes have become extremely expensive and hard to find. The Svetlana EL509 is similar in characteristic。
3、 The failure prone parts in the TF12 are the optical encoder volume control, 1Meg resistor in the mute time out located 。
4、 The failure prone parts in the EA2101 are the four 150K resistors in the feedback sensing. Early versions used carbon f。
