jedyne do czego mogę mieć zastrzeżenie to jakość zdjęć zawartych w przesłanej instrukcji serwisowej ponieważ są fatalnej jakości, praktycznie nieczytelne. tak poza tym jestem zadowolony to jest to czego szukałem.
 ;
Wszystko w porządku.
Instrukcja czytelna i kompletna.
Dziękuję.
all right!
thank you.

4 SOUND OUTPUT STAGE TDA2822 TDA2822 is used as the AF output amplifier. It is supplied by +12VDC coming from a separate winding in the SMPS transformer. An output power of 3W(THD=10%) can be delivered into an 16 ohm load. 5 VERTICAL OUTPUT STAGE WITH TDA8174A TheTDA8174Aisa power amplifier circuit for use in 90° and 1 1 0 ° colour deflection systems for 25 to 200 Hz field frequencies, and for 4 : 3 and 1 6 : 9 picture tubes. 6 POWER SUPPLY (SMPS) The DC voltages required at various parts of the chassis are provided by an SMPS transformer controlled by the 1C UC3842/ 3 which is designed for driving, controlling and protecting switching transistor of SMPS. The transformer produces 1 1 5 V for FBT input, ±12V for audio output 1C, S+5V and 8V for ST92195. 7 DISCRETE VIDEO AMPLIFIER Three high voltage, high frequency transistor is used for RGB amplifier. This application works on fixed AC and DC gains.
