Berning-EA2100-pwr-sch维修电路原理图

1、 For units set up for 240 volts, a 50 ohm-10W resistor is inserted in line with the incoming mains power. CAUTION: Dangerous voltages are present inside the TF-10. Servicing should only be attempte。

2、 The 6LF6 output tubes have become extremely expensive and hard to find. The Svetlana EL509 is similar in characteristics, and with a substantial amount of work the EA-2100 can be changed to take 。

3、 The failure prone parts in the TF-12 are the optical encoder volume control, 1Meg resistor in the mute time out (located on the power supply board), the HER602 diodes in the power supply, 470 F c。

4、 The failure prone parts in the EA-2101 are the four 150K resistors in the feedback sensing. Early versions used carbon film resistors that tended to increase in value, or go open completely, caus。
