Replacement Power Supply for 8-bit Atari (800/130XE)

[ralphw]

(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.

I'm not sure the 800 transformer types have much in the way of problems.

They work or they don't - a pair of windings that give a predetermined output voltage without altering the AC waveform, so not a lot to go wrong.

But of course you have the computer side power board where most of the action takes place so that's where a failure is more likely.

 

The later XL and XEs - you can homebrew a USB cable to DIN plug and use a > 1 Amp (probably preferably > 1.5) 5V DC charger.
