  1. Hi @Cmherndon79, I replaced another TIA and the problem is solved 🙂 Thanks a lot for your suggestion.
  2. Hi Cmherndon79, sorry for the confusion, I don't mean directly from the pin. What I have tried is to follow the 2 guides below to install the AV mods: 1. http://www.coolretroprojects.com/Atari_2600_AV_Mod_Installation_Guide.pdf the instruction asked to tap audio from TIA pin 13, before C210. 2. https://www.thefuturewas8bit.com/atari_2600_6_pal the instruction asked to remove R209, and have the audio tap from one side of the removed resistor, after C210 I have tried the above 2 with the same result. In both cases, I believe the audio signal will not pass through C206 and C207 as I have already removed R209. I have attached the PAL schematic diagram that indicate where I tap the audio signal.
  3. Thanks for the suggestion, but this is a AV modded unit, the audio goes directly from the TIA PAL pin 13.
  4. Hi, I have an Atari 2600 6 switcher PAL that produces distorted audio about 1 minute after power up, and slowly loses audio after few minutes into game play. The problem persist even powering off and on again. The audio will be ok again after leaving it unplugged overnight. I have attached a video of how it sound. Note that this Atari 2600 is AV modded, so the red coil has already been removed. Both the RIOT chip and TIA chip has been replaced recently. Here are a few things that I have tried but doesn't help: 1. Change another 9v power adaptor 2. Make sure power toggle button has good connection 3. Checked output from the power regulator is always 5.1v Hope to get some pointers as to what are most likely cause of the problem. Thanks in advance! pacman1.mov
