I have a small travel board, with a 18V / 500mA power supply attached to a 18V/9V (capable of passing 1.5A) distributor I made. I keep a spreadsheet of my boards and track their current requirements, never loading more than 70% of the supply's max.
I have a band reunion coming up and will be playing out of my 1972 Marshall SL100, to which I put a Dunlop Mini Cry Baby, an EHX Tuner, a Pro-10, an Arachnid, a Catalinbread Echorec, an EHX Oceans 11 and an Episode Booster. I was experiencing intermittent drop out with the Oceans 11 and noticed the supply was warm.
I estimated the tuner to be around the same current as my 1980's Arion tuner (40mA). I was WAY off. The EHX 2020 tuner is using 180mA when bypassed and 250mA when in use! My total demand-draw was around 670mA.
I began researching and checking my other newer tuners and even my Korg Blackout Custom tuner was around 200mA! It makes sense that the displays use a lot of juice, but it didn't dawn on me these were so power hungry.
FWIW: I put the tuner on its own supply and swapped the main supply with an 18V / 1.8A.
