Bench supplies for heaters

Very good idea to have some adjustable bench supplies for low voltages. I have a bunch of 30v, 2A adjustable supplies. I only use filament bias with 4P1L tubes - nothing else anywhere. So it's an easy step to just dial in the voltage. For two tubes in parallel for the output of my PSE amp it's 28v at 1.2 amps. Simple.
