 SA203/K TECHNICS Service Manual by Stu Williamson;
This is the ONLY copy of this manual I could find for a realistic price. Even Panasonic could not provide me with one. The PDF is a very good copy and it helped me diagnose and find the fault with the unit I have.
 SL-JS16R TECHNICS Service Manual by Francisco Oliveira;
Very complete and well reading drawings. Documentation is essential for successful repairs.Good documentation, with all that is necessary. This manual was what I was waiting with all the information necessary for the repairing I need it for. You must buy it if you want to do repairs or simply understand how it works.
 CSC-950 CROWN Service Manual by Gabriel Popa;
Excellent service manual includes everything is need to repair this radio-caseete, how to disassemble, wiring diagram, all , waiting time until the download was only a few hours. I'm going to buy service manuals from here, are cheap and very good.Thank you.
 KDD20 JVC Service Manual by Gabriel Popa;
Good service manual,i saved from scrapping this deck,is now fully functional.Thanks.
 DEH-P2000/XQ/UC PIONEER Service Manual by Steve Kohler;
Found this to be the manual included with the original packinging, was helpfull but did not give any detailed repair instructions.

The shorter the pulse ON time is, the higher the CLV is, and vice versa. The pulse ON time rises at the zero-cross timing of AC and is driven with duty. Positive pulses the copy lamp ON signal are generated by C248 (C253) at falling of the CPU output and inputted to the photo triac through the 2-stage transistors.

(11) Power section
This model is provided with the auto shut-off mode. The power section is also designed for it. When the power switch of the copier is turned on and the AC power is supplied, AC waveforms for +5V power are generated in the secondary side of transformer T301. The AC waveforms are full-wave-rectified and smoothed by diode BD102 on the main PWB side, and 5V is generated by 3-terminal regulator of IC111. The 5V power is supplied to the CPU. When the CPU is actuated by the 5V power, it starts the switching power to output the SWPEN signal (CPU output: LOW). The switching power outputs voltages of 24V and VBS with this signal. BVS is stabilized by IC112 to become a voltage with stable BV, and is used for LED display. 24V is supplied to the motor and the solenoid, and supplied also to the 3-terminal power for 5V through D144. When the CPU turns off SWPEN to enter the auto power shut-off mode, 24V and VBS output falls near zero, virtually turning off.

* At rising of the CLPWM signal (V4), the coy lamp is switched by the triac. The trigger signal Cl is sent to the triac to turn on the lamp. Then the lamp is turned off at the zero-cross point of V1 waveform. The CPU reads the control voltage level (QV) corresponding to the change in the copy lamp voltage The CLV produces the waveform equivalent to the copy lamp voltage waveform which disables the full-rectified waveform of AC input during the pulse ON time. The waveform is converted to the DC level by the low pass filter composed of C102 and R105, and inputted to the CPU. The relationship between the CLV and the pulse ON time is shown in the figure below.
