Separate PSU?

Posted by UK Ray (A) on July 30, 2004 at 03:31:02

I've often toyed with the idea of seperating the power supply of my paraglow amps into a seperate box - keeping AC supplies away from signals seems like a good idea and it gives flexibility for future experimentation. I need to buy a new mains transformer to facilitate windings to power a DC heater supply for the 2A3s so the opportunity has arisen to put this into practice.

To maximise the benefits of seperating the units I intend rectifying the AC to DC in the PSU box, feeding DC to the amplifier via umbilical cords of not more than 60cm (24ins) length. That way potentially hum inducing AC is simply not present in the amplifier. Is there a downside to this - I know DC drops volts over a cable, but they'll be fairly short so this shouldn't be too significant.

Thanks for any thoughts or advice.
