Hi, Not sure which instrument you need the power supply for, but the Pocket Pianos, Bolsa Bass, Kaleidoloop, Septavox, Video Scope, Rhythm Scope and B&W Video Scope require an external power supply must have the following output specifications: 9VDC, a minimum of 300mA (0.3Amperes) and a 2.1mm barrel connector with center-positive polarity. The center-positive polarity diagram looks like this: ![](https://canada1.discourse-cdn.com/flex035/uploads/critterandguitari/original/1X/572ce49bf607a39d0854d868f912a0ad2c1956cc.png) Many guitar pedals use power supplies that are very similar to these specifications. However, they often have a tip with center-negative polarity. These will not work unless you get a reverse-polarity adapter for it. One-Spot, Boss and Roland supplies are typically center-negative. You may use a power supply that outputs more than 300mA, but not less. Only 9VDC should be provided to the instrument. Voltages above or below 9VDC will cause damage to the instrument. Thanks! ---

Got it. The polarity image is hard to see. Not sure it has the required center-positive polarity. This one looks good too: [9VDC Power Adapter](http://www.amazon.co.uk/STOREINBOX-100-240V-Charger-Supply-Adapter/dp/B00SF4NNZ2/ref=sr_1_1?s=computers&ie=UTF8&qid=1448384636&sr=1-1&keywords=9v+dc+power+supply) ---

I’d like to use a UK adaptor - connecting with a travel adaptor is a bit flimsy - and adds a lot of bulk in my mass of wires and cables. I found what I believe is the UK version of the official adaptor GT-86121-WWVV.V-W2U Wall Plug-in ITE Power Supply > **[GT-86121-WWVV.V-W2C Wall Plug-in ITE Power Supply Datasheet](https://en.globtek.com/model/ite-power-supply/wall-plug-in/gt-86121-wwvv-v-w2c/a0Oa000000PSQ1yEAH)** > > GT-86121-WWVV.V-W2C, ITE Power Supply, Wall Plug-in, Regulated Switchmode AC-DC Power Supply AC Adaptor, , Input Rating: 100-240V ̴ , 50/60Hz, China GR 2099 configuration: 2 pins, Class II, Output Rating: 12 Watts, Power rating with convection... > **[GT-86121-WWVV.V-W2U Wall Plug-in ITE Power Supply Datasheet](https://en.globtek.com/model/ite-power-supply/wall-plug-in/gt-86121-wwvv-v-w2u/a0O0c00000PGGZTEA5)** > > GT-86121-WWVV.V-W2U, ITE Power Supply, Wall Plug-in, Regulated Switchmode AC-DC Power Supply AC Adaptor, , Input Rating: 100-240V ̴ , 50/60Hz, UK BS 1363, 2 Blade w/Dummy Ground Class II, Output Rating: 12 Watts, Power rating with convection cooling... - Can’t find an importer that has it yet. it is a clear this is a part - not a complete adaptor - it can be set to anything between 4 and 24v in 0.1v increments, and lacks the 5.5mm x 2.1mm centre positive barrel plug.
