Battlezone sound problem....Only half the sounds present
I bought a battlezone, and it works great except for sound. It plays great, however, exactly half of the sounds are missing. The tank motor sounds good high and low, and the enemy and my tank fire sounds work. All the explosion sounds work.
The missing sounds are the alien sauser and alien guided missle sounds, the radar beep when a new tank appears, and the tune at the end if the game. The last 2 deep thumps of the tune work, but the begining of the tune is silent. When game is over, 10 seconds of silence (missing melody), then "boom, Boom". I saw the audio board has two TDA 2002 amps. I figured one must be bad. I replaced both, with no change. I ordered a bob roberts audio board rebuilt kit, and atari power supply kit, and rebuilt both the power supply, and audio board plus two new TDA 2002 amps. Still no change. Any suggestions? The sounds I have are coming through all 3 speakers, 2 overhead, and one lower left front. Thanks for the help. Also no Ram beeps during startup in test mode. All else checks ok on screen test display.
