(edited - the Atari 800 supply is a 9VAC transformer)
I have four Atari 800s and one 130XL I've accumulated over the years. I'm getting nervous about using the original 1980s-vintage power bricks,
and wonder if I should replace any of the supplies.
I lack one of the Atari 800 supplies, and wonder if I can build a replacement. What's a reliable source for the transformer Atari used.
For the 130XL, what should I be looking for? Do I need to worry about the aging internal components in the 800?
I see warnings about the "ingot" power supply, so will avoid that.
