Hi, What is the best power adapter to get for the UK, Thank You

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:

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!

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

  • 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.

I’m wondering if this item from would be an acceptable substitute:
