nice completed SERVICE MANUAL as the description THANK YOU !!!-
;
Hard to find service manual describing the PLL circuit of the AKAI AP-306.
Thanks to have it available.
;
Gut, sehr gut! It helps me much! I couldn't find this schema nowhere. Good quality
DESCRIPTION OF SCHEMATIC DIAGRAM
VOLTAGE MEASUREMENT CONDITION:
SCHEMATIC DIAGRAM
1. When the exclusive-use AC adapter is used, the colour bar signal of colour bar generator for service is input to get the normal screen. When the audio is minimized, the voltage value is measured with the 20 k�/V tester.
WAVEFORM MEASUREMENT CONDITION:
Models
LC-26GA5U LC-32GA5U
1. When the exclusive-use AC adapter is used, the colour density, lightness and colour hue are set to the center position, and the signal of colour bar generator for service is observed to get waveform.
INDICATION OF RESISTOR & CAPACITOR:
RESISTOR 1. The unit of resistance ��� is omitted. (K=k�=1000 �, M=M�). 2. All resistors are ± 5%, unless otherwise noted. (J= ± 5%, F= ± 1%, D= ± 0.5%) 3. All resistors are Carbon type, unless otherwise noted. C : Solid W : Cement S : Oxide Film T : Special N : Metal Coating CAPACITOR 1. All capacitors are mF, unless otherwise noted. (P=pF=mmF). 2. All capacitors are Ceramic type, unless otherwise noted. (ML) : Mylar (TA) : Tantalum (PF) : Polypro Film (ST) : Styrol
