About :
First of all, engine and mechanics maintenance! Then design flaws, electronics later. It's not a problem if there is no original engine and electronic board, we'll do everything ourselves. An external stabilizer with a Schottky diode and LM 7810 will eliminate many problems, feed to L3 L1 and (jumper L2-L5 if 10 volts remove D5), and D4 can be left as reverse polarity protection. AGM LP 12 - 1.3 AH battery can also be used. Later I used KIA7809. I also advise you to look at • KIA78R09 in UNITRA G602, photostop works well, but when you want to listen to the last tracks again, it works. An unpleasant little thing needs to be eliminated! An optocoupler can easily switch a solenoid, the current of its transistor is 50 mA, start and stop will disappear since the position of the tonearm will be the control. The signal for the sensor can only be removed from the disk!!!
