IV.. Explanation for modification 1 .Vertical size is too large or too small: When you do installation and adjustment, you can adjust the value of resistor R45 1 (8.2K-3.9K). When R45 1 increases, vertical size decreases; when R45 1 decreases, vertical size increases. At the same time adjustment of vertical size in the bus control is supplemented until a satisfactory result is obtained. 2.Horizontal size is too large or too small: When you do installation and adjustment, first of all, you should change the position of horizontal deflection lead (red wire) plug. You can select among Tl, T2 and T3. Select a socket with a relatively low deviation. Then you can appropriately adjust the capacitance of return capacitor C438 and C435 (adjustment in a small range) and the capacitance ofS-correction capacitor until a satisfactory result is obtained. V. Important information 1 -The intermediate-period of intermediate-frequency Audio Frequency Transformer (AFT) in the chip of the model has been precisely tuned to 38M before shipment. Do not adjust magnetic core of TlOl too quick in order to avoid abnormal functioning of the model. 2.Before turn the model on, check if the ground wire of display tube is securely connected to the ground wire socket of the tube base 3 .If the value of field deflection resistor of display tube you use is too high (about 50 Q), you can change the field deflection from serial connection to parallel connection. 4.YDT6 13-B (3 W8Q) speaker should be used.
