Default Re: Advice needed on choosing a power transformer

You need about 50mA DC per channel. That 370DAX will be OK if the 100mA rating is for rectified DC, not RMS AC. The mention of 76VA may imply that the current is a DC rating, but it would be helpful if manufacturers were clearer in their datasheets.
