Bela sent me a couple of faulty ASTRO WARS boardsets....
Set A: working but a line on the screen, sound board not tested
Set B: not working, sound board not tested.
70% of my time was dedicated to rebuild the wiring

but the I could make some tests.
1) EPROMS: one from Set A and 2 from Set B were faulty. I reburned them
2) Set A had a problem with a CPU socket
3) after cleaning all pins and sockets Set A was completely working, sound board included.
4) after EPROMS changes and one 2708 socket replaced I could see game working but with corrupted graphics
5) Changing graphic RAMs (3x2114) the game works properly
6) substituting a couple of capacitors was enough to have the second sound board working.
