Right. The only difference is the transformer and consequently the output
power (1200mA instead of 650mA) and the (mechanical ) hum noise. The rest of
the power supply electronics is identical for both types. It is even
possible to replace the standard transformer by the new ring core
transformer (recommended only for users who are experienced with electronics
and soldering).
