I assume they’re both 24 volts DC, center-negative? If so, you could use one of the Voodoo Lab Pedal Power supplies that has two or more 12 v DC outputs and is up to the current-draw of your two pedals, and connect two 12vdc jacks to Voodoo Lab’s “Voltage Doubler” adapter Y-cord, to provide 24vdc. You would need two 12vdc outs and one Voltage-Double Y-cord PER 24VDC PEDAL, though, not all of Voodoo Lab’s power-supplies have more than two 12vdc output-jacks…

Note that you may or may not have to use some sort of small, inexpensive in-line female-to-male adapter or cable to connect a Voodoo Lab power-supply cable to your given EH pedals; I don’t know what size and style/shape jack and plugs your EH pedals have… The VL ‘site has a LOT of info to help you figure out what you do or do not need; I’d be glad to help, as well, if you can’t find the info you need there.

(And by the way, I am NOT spamming or shilling for Voodoo Lab here, I don’t work for them and am not connected to or associated with VL in any way; I’ve just been very happy with the VL products I’ve bought- my rig is the quietest it’s ever been!- and I’d had to figure out some of this stuff before for myself.)

The large, rather pricey but very “pro” Voodoo Lab Pedal Power ‘MONDO’ power-supply has a number of outputs that are switchable between 9vdc and 12vdc; though some may or may not be up to the current draw (ma, milliamps) of your given pedals- just which two EH 24vdc pedals do you have, and what is the current-draw of each pedal (not necessarily the same as the current capability of the individual power-supplies)?

Two Voodoo Lab Pedal Power ‘DIGITAL’ power-supplies would likely cost a little bit less than one ‘MONDO’, but you’d also have fewer total power-supply outputs to potentially use for other pedals.

A pair of VL ‘DIGITAL’s would let you power two 24vdc pedals and leave you with a total of four more 9vdc outputs, all four of which would be relatively “high current” capable.

A pair of Voodoo Lab ‘4×4’ power-supplies (together more expensive than one ‘MONDO’) would let you power two 24vdc pedals and still leave you with a total of twelve more 9vdc outputs, four of which would be relatively “high current” capable.
