Does anyone here know how to purchase these chips? Best Electronics said he sells them in tubes? not by the each? And ebay... Anywhere else????? thanks....

Thanks crosbow. I dont think my mod install was bad. And sure not bad twice. Its pretty straight forward. I thought I may have done the VR backwards as well but it wasnt. And once I removed the mod it wasnt burning hot. I am learning electronics now as well. Maybe some solder was crossing over to wires but I just dont think so because same results twice.

Thanks to all of you who responded and helped out.. and your info did help.... I also got a hold of the Atari Field Service Manual and I think I could be an atari Tech now!!! (not really, but it is amazing to have) I replaced some swithes and had done a video mod and the video went dark, could still see the video but the color was all bad. I was sent another one, so I replaced it and I was sent a Sixer Refresh kit. Thats when the real fun started happening. My Polarity is/was good. I troubleshot everything so much, i even used a different power supply and got nothin. Then I decided to lose the Mod and go back to the original set up. It seems the voltage regulator has gone to a normal temp and my color is all back to normal... For now! Im super bummed because now my Heavy Sixer has 3 composite mod holes in the back and Im actually all good with the RF cable, I was a bit too ambitous. Just wanted to update anyone who saw this and say thanks but I'm sure I'll be back picking your brains soon!!!!

This is the voltage regulator solder.

Thanks for the quick response. Please explain further on observing polarity on the caps... Im going to check the solder now!

Hey yo! So, I did a video mod. It worked well for a bit then all the colors went very dark. No adjustments would work. I was sent a replacement mod and a sixer refresh kit. I replaced the video mod possibly it was a bad pcb but no change. I then started to do the refresh. I replaced the 2200 uf capacitor and no change in color. I then replaced the chicklets, C103 and C104 and the voltage regulator, A101...... Now I get no video at all and the voltage regulator is burning hot! Also the original power supply started clicking but it stopped now. I think it was over heating as well...... any ideas my friends??? Im getting ready to give this thing up!

Thanks for all the info everyone. I learned what I needed.

I recently purchased a heavy sixer that needed some TLC. I just bought a game select and reset switch on eBay. I received THEM and they are much smaller than the original. The 6 prongs line up but the casing is much smaller. Could this be an aftermarket part? Or just manufactured different. One says toyo on the side and the other says Hudson Taiwan R.O.C. Is it cool to solder on or should I get one that matches. I can't see where to post a pic as this is my first atariage post!!!
