Hello,

Based on the power supply chapter in Morgan Jones' book, which is very similar to this one from a previous thread:

http://www.diyaudio.com/forums/atta...-troubles-when-elevating-lt-supply-supply.png

Can elevated heater supplies be used as shown for the LT section of the supply (at the above link) but with a center tapped transformer rather than the dual secondary as shown in the circuit. I know that dual positive supplies are possible but will the lack of isolation be problematic with the elevated heaters?
