  1. finally after a lot of work i discovered the defect in the audio that was causing problems in the sound of kicks, voices etc. after changing oki chip, z80, all capacitors, 4 ci 5218a, ci yamaha ym2151, chip ym3012 among others, I found that the defect was simply resistor R47 (2.2k). problem solved and sound working perfectly.
  2. replaces ci 13001 as well. no results. the music works perfectly. the kicking sounds and voices don't work
  3. l already made the exchange of all capacitors, z80. oki, ym3012, but to no avail
