The main power supply diagrams in AE-6B chassis are shown as 
Figure 2.2 and Figure 2.3. It is similar to FE-2 and LE-3 chassis. 
Meanwhile, the power supply circuit for AE-6B and AE-6D chassis is 
almost similar. The difference is there is an additional G1 board in AE-
6D chassis.  
 
 
 
 
 
 
 
 

 
 
 
 
 
 
The primary power supply on the AE-6B chassis G board consists of 
three parts:  
1. Oscillator 

 

2. Output stage 

3. Regulator Stage 

 

The oscillator starts up to produce an initial signal for the output stage. 
The output stage develops voltage to continue running the oscillator 
stage, supply the regulating stage and provide normal output for the 
TV. One of the normal TV outputs is used to start the secondary power 
supply.  
 

 

The oscillator within IC6001 starts if the VSENSE input voltage at pin 1 
is above 1.3 VDC but less than 8 VDC

. 

The block diagram of IC6001 is 

shown in Figure 2.4.  

 

Sample voltage from pin 18 is then used to run the internal oscillator. 
The initial frequency is approximately 230 kHz. The low amplitude 
initial oscillator signal is output IC6001 / pins 12 and 16 into the 
driver/output stage.
