Information about the Jaguar and Jaguar CD power supplies:
What are the specs for the original Jaguar power supply?
9VDC 1.2A output center negative. Do NOT use a center positive power supply or the Jaguar will be damaged.
What are the specs for the original Jaguar CD power supply?
They are identical to the Jaguar console’s power supply.
Do the PAL units use different power supplies?
Only the input voltage will differ, the output specs will be the same.
Where can I buy an original Jaguar or Jaguar CD power supply?
What other common power supplies can be used?
Anything with the above specs will work, though it is not recommended to go above a 10V output. The most common solution is a Sega Genesis/MD Model 1 power supply, any of the 1602 models will work.
Anything to be aware of when using a non-OEM power supply?
If you are using a Skunkboard rev1 and 2 boards, do not exceed the rated 9V output as the unregulated output is passed directly to the flash chip via the cartridge connector.
Are there any single power supplies that will power the Jaguar and Jaguar CD at the same time?
Any power supply that has a 9V center negative with an output of at least 2.4A should be suitable for this purpose. A Y-cable of the proper size (5.5mm OD x 2.1mm ID) can be used.

Troubleshooting a possible power problem:
My Jaguar doesn’t turn on, what’s wrong?
1. Do you have a cart in the Jaguar? If not, it won’t power on.
2. Start with the power supply itself. Are you using one with the above specs? If so, verify it is working correctly using a voltmeter or by trying it on another Jaguar, Genesis Model 1 or Sega Master System.
3. You may be using a dirty cartridge or your cartridge connector may be dirty. There are two pins on the cartridge connector that must complete a circuit via the cart itself in order for the Jaguar to power up. If this only happens with certain games, it is most likely an issue with dirty cartridges.
4. If you received the console used/untested and it does not power up the most likely cause is a blown voltage regulator as a result of hooking up a power supply with the incorrect polarity.

The parts are not custom and should be available from any local component supplier (Mouser, Digikey, etc). They are also stocked at Console5.
