Does anyone work on Atari (Gen 2) boards? Or at least give me some
advice on what may be wrong with this Superman I am currently working
on. Plays good, sounds are off. LEDs on the cpu light as they should indicating it thinks its playing the right sound(s).

Hi Paul,
Sounds are amplified by the Lamp/Sol/Audio board, did you check for
12VDC at that test point?
A simple audio tracer will help a lot here. There are many suggestions
on youtube. I've played with using PC style amplified speakers with reasonable success.
I also service Atari board, but try my suggestions first before shipping
to Canada. Also check the speaker wiring from the Lamp/Sol/Audio board,
you may have a simple connection problem!

Have 12v (well, 10.9vdc) at the lamp/solenoid/audio board.
I'm figuring something like this?

Since the sound consists of the noise generator and waveform generator > (The Atari sound setup on the mpu), I would test after these are
combined to see if I hear proper sounds before going to the driver/audio board?

Hi Paul,
Sorry, I'm not going to dig through a 14 minute video to try and figure
out what you want me to see. Tell me the minute:second reference please!
If the video talks about an audio sound tracer, then yes, that is what I suggest for following the audio...

After watching where he probed around, made me think of where to go
about on this Atari board, which is why I asked your opinion on where I should probe around. Thank you for any input.

Hi Paul,
Yes, that can work - using a PC speaker - but they aren't terribly
sensitive to low volume sounds.
As for where to probe, you need to use the schematic and then use that
to help identify the audio sections and ICs and use the probe while attempting to make sounds.

I made my probe and started poking around after looking over the schematics and reading the manual.
So Atari did not screen the boards with what component is what. (kinda like Williams did back in the system 3-7 era, but Williams at least
provided board layout and labeled every component in the schematics).
I looked around and can find nothing like this for the Atari boards.
Makes it hard when you read the schematic and manual and go to test Q2 > and have kind of zero idea where it is.
So, by chance do you have such a layout of these boards?

Hi Paul,
The parts manual for the game shows the locations of the components.
You could try the audio tracer on the audio ICs first, to hear what sort
of sounds you are getting there.
