skidder652003 Posted November 10, 2019 Share Posted November 10, 2019 (edited) Hi folks Im thinking of getting one of these Donner Power Bricks https://www.amazon.co.uk/Donner-Guitar-Supply-Isolated-Output/dp/B0778GPWMR/ref=asc_df_B0778GPWMR/?tag=googshopuk-21&linkCode=df0&hvadid=310810391039&hvpos=1o2&hvnetw=g&hvrand=10006950394915424542&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9045321&hvtargid=pla-564314077153&psc=1 as Ive been having some issues with a dodgy 4 way plug to power all my effects off the pedal board and looks really ugly. Everything is 9V (tuner, phaser and compressor) except for my DHA VT2 EQ which is as follows "The VT2-Twin-EQ-Std-Bass has a two built-in voltage doubler circuits; this generates 24V from the existing 12V power supply. The 24V is used to supply the anodes or plates of the valves, two are used to ensure good power supply decoupling between channels. The VT2-Twin-EQ-Std-Bass is fitted with 2.1mm external PSU adaptor for use with a 12v @1200mA external supply. The user should use a well regulated external supply as the better the regulation then the less the hum when at higher gain levels. If you find there is alot of hum at high gains then the problem will be the supply is not well regulated. I have found that Switchmode supplies work well and these are standard for higher current types, so it is likely that any 12V supply over 1.2 5A will be a switchmode. The inner of the connector is the positive, there is reverse polarity protection so no harm will be done if you get it wrong." Blimey! I have no idea if this pedal would work off the Donner, anyone the wiser? Any advice, as ever, greatly appreciated.

itu Posted November 10, 2019 Share Posted November 10, 2019 This is very easy. If your pedal needs 1200 mA (1.2 A), 500 mA is not enough. Far from it. 1 Quote Link to comment Share on other sites More sharing options...
