+madman Posted July 12, 2017 Share Posted July 12, 2017 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? B&C ComputerVisions Best Electronics The Goat Store 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. One supplier of an all-in-one PSU that is ready to use is here: Retro Game Supply 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. AtariAge member SCPCD wrote up an excellent guide on the parts that have likely suffered damaged: http://scpcd.free.fr/jag/jag.htm#Repair The parts are not custom and should be available from any local component supplier (Mouser, Digikey, etc). They are also stocked at Console5. 13 Quote Link to comment Share on other sites More sharing options...
+Stephen Posted July 12, 2017 Share Posted July 12, 2017 Is it true that the Jag power supply was not a 64-bit supply, but merely two 32-bit power supplies running in parallel? 14 4 Quote Link to comment Share on other sites More sharing options...
+save2600 Posted July 12, 2017 Share Posted July 12, 2017 Its fatal flaw is that it should have had a heat sink or three for all that powa! 1 Quote Link to comment Share on other sites More sharing options...
grimm Posted August 1, 2017 Share Posted August 1, 2017 Telegames.co.uk sell the power supplies for us who are in Europe. The above mentioned retailers are all in North America. 1 Quote Link to comment Share on other sites More sharing options...
Orionis5 Posted November 19, 2017 Share Posted November 19, 2017 Hello, I'm looking for EU plug jaguar power supply. American sites are no no since even if they have EU plug it is too expensive for buy. Telegames has UK plug power supply and no specifications on it if it is OK. Voltage is OK, only need to change plug. Is it OK ? What about this one on ebay ? http://www.ebay.de/itm/Transformator-Atari-Jaguar-Stromversorgung-macht-Macht-Power-Versorgung/202060414019?hash=item2f0bbd3c43:g:X8gAAOSw6HJZwQAl Thanks Quote Link to comment Share on other sites More sharing options...

Eltigro Posted July 16, 2018 Share Posted July 16, 2018 The power supply for my Jaguar will start buzzing after a while. As in, the wall wart itself will have an audible buzz/hum coming from it that gets louder the longer it is left plugged in. It seems to power the Jag okay, but it worries me that it may damage the Jag or that it is a sign that the power supply itself is about to go out. Any ideas? Just get a new one? It is an actual Jaguar part, not an aftermarket one. Quote Link to comment Share on other sites More sharing options...

Have you checked the voltage from it? Quote Link to comment Share on other sites More sharing options...
Eltigro Posted July 21, 2018 Share Posted July 21, 2018 Nope. Don't have a multimeter. May be able to take it to work and check it. Quote Link to comment Share on other sites More sharing options...
UHATEIT Posted January 7, 2019 Share Posted January 7, 2019 This was very helpful actually. I am trying to help out a local guy that got an untested Jaguar that will not power on, he has tested all the cables and everything apparently is fine but it will not power on. Likely it's that U38 chip then as madman linked to that one page. Very helpful and useful info! Quote Link to comment Share on other sites More sharing options...
pkerga Posted February 4, 2020 Share Posted February 4, 2020 (edited) My Jaguar power supply delivers 13V.

+madman Posted February 4, 2020 Author Share Posted February 4, 2020 That's not under load, try measuring the input voltage to the Jag when it's powered on. Even so, the regulator can handle much more than 13v input. Quote Link to comment Share on other sites More sharing options...

EddieHitler Posted March 16, 2020 Share Posted March 16, 2020 (edited) What about the Jag games for sale at Telegames.co.uk - I take it those are repro’s? Just I notice they have Worms for a fairly reasonable price. http://www.telegames.co.uk/shop/index.php?route=product/product&product_id=5436 looks slightly fishy to me...

+-^CrossBow^- Posted March 24, 2020 Share Posted March 24, 2020 Wanted to ask some questions on here in case anyone might have some additional input on things to look at. I've got a jag sent to me for replacing U38 (Blown regulator). I did this and also replace out C134 as that had obvious heat stress along the side of it. The jag powers up but no audio at all. In looking at Reg1 I am showing +12 to the Vin pin 8 but only about .8v on the Audio VCC out on Pin1. Thinking Reg1 is likely dead, I went ahead and supplied +5 straight to TP6 where the Audio VCC out should be and that only causes the jag to not boot at all. So now I'm not so sure that Reg1 is to blame. For the record that IC physically looks ago although I did hit the pins with fresh heat in case they weren't all making good contact. Is there somewhere else I should apply +5 to the audio circuit to try and get audio working again? Does applying +5 directly to where pin 1 on Reg1 attached to the main board and preventing the jag from booting indicate some short? If so where? because in continuity mode, I get nothing from ground to pin 1 of Reg 1 nor in resistance mode. But in Diode mode, I do show 1v from ground to pin 1 on Reg 1. I also confirmed on the 1545 that the audio VCC in is the same .8v reading I get from TP6 so that at least appears to be good to that point. Also not showing any dead shorts from ground to pin 8 of the 1545. Ideas? NM - Got it going. Turns out where I was getting my +5 from, the Jaguar didn't like. Works fine bypassing REG 1 using Pin 1 off the ADC directly. Problem solved... 1 Quote Link to comment Share on other sites More sharing options...
Sapicco Posted April 19, 2020 Share Posted April 19, 2020 I bought a cheap nes several months ago. It sat in a box for a while. I noticed today they guy I bought it from sent a jaguar power supply. It’s different than the one I have for my jaguar. Anyone one know why they are different? Quote Link to comment Share on other sites More sharing options...
Maico Posted August 10, 2020 Share Posted August 10, 2020 Hello friends. I bought an Atari Jaguar on the craglist for 100 $. But the person only had the console and a control. I asked how she knew it was working, she said it was, because the last time her son used it, it was a few years ago. So I bought the power supply on ebay and it arrived today. I tried to turn on the jaguar without a cartridge and nothing happened. I am waiting for the cartridge to arrive Wednesday. I tested the power supply with a multimeter before connecting to the atari saying 11.5v. This is correct? Without a cartridge connected, does the jaguar not turn on the light indicating that it is on? Thanks 1 Quote Link to comment Share on other sites More sharing options...
Zerosquare Posted August 10, 2020 Share Posted August 10, 2020 (edited) The Jaguar won't turn on at all without a game inserted, and the no-load voltage of the official power supply is known to be significantly higher than 9V. Nothing to worry about Edited August 10, 2020 by Zerosquare 1 Quote Link to comment Share on other sites More sharing options...
