1.25A is the upper limit of amps, found on some OEM PSUs.
I still say contacting CYP Europe may yield fruit.

They were the official importer of the Cypress CTB-100 and CTB-100G, which is what this was before rebadged.
The black AVT-8710 has the same power ratings, as do/did some other Cypress gear.
The other option is a branded PSU, center-positive, using a polarity reversal cable. I've used those, can confirm this works. (But note it must be good PSU, good reversal cable.)
- No unbranded units, not a "for __" Chinese adapter
- No multi-volt model (those with little dials to pick volts), as it always has noise, (power leaks, poor shielding)
Hopefully another Europe user has details on exactly what and where. I know others here in the forum are there, and use this exact green units. Some even in Netherlands specifically.
