I have Eros 2. What are ratings in amps of the power transformer 9V and 140V rails?
Thanks.

That design is more than 10 years old, and I would not rate it today the same as I did back then. I've learned some things since then, and should probably re-evaluate this design.

Today I might rate it 2.6Arms for the "9v" winding and 0.14Arms for the "140v" winding; I can't be sure without making and analyzing some new measurements. We use it a bit harder than that in Eros, and as far as I know we have not had any issues except for the high surface temperature, but I'm reluctant to quote the Eros conditions as a safe rating.
