Total recall dc jack size and grounding question

[sarde]

I see the total recall (DMM) calls, in the build doc, for using the ehx 24v wall wart. Correct me if I'm wrong but that is a 2.5mm plug not the standard boss 2.1mm plug most pedals use.
So, I need a 2.5mm dc jack, not a 2.1mm?

Now, I might be wrong, but with the pedal being positive ground, if I used a metal bodied dc jack that would ground the negative sleeve to the enclosure; which would be bad since the audio jacks ground plane contacts the enclosure then connect to the board, which is positive ground; thus, connecting the positive and negative together. So, do I need a plastic bodied 2.5mm dc power jack?

Sorry for the dumb question; but I want to be sure I don't blow everything up.

no the ehx is a 2.1mm connector, same as boss-style connector

yes, you should use an insulated jack.

Hi Sarde.

You need 36V DC (24V power tranny +bridge rectifier+1000uf/50V) Min.250mA
