Many thanks. As I do not anticipate using the supply at 3A a lot, nor for long periods I think I will go for this option and just be sensible about suitable cooling.
You do a great job on here, I am sure that many other appreciate your advice as well.
All the best
Hi, just trying to source a transformer for this.
RS do a 2x15V 4A essentials toroidal transformer. I realise that this only rates at 120VA rather than the 126VA recommended. Is it possible to use this? If so what effect will the missing .2A have on the output?
