Transformer for Tube Amp - Gold or Junk?

[Shadetree Mechanic]

We are dismantling an old production line at work, and one of the pieces of equipment had these neat transformers. They are step down to provide power to control circuits and motor power. They have a 600v primary and I was wondering if I could power the secondary with line voltage to use as a step up transformer? Even the little one is heavier than it looks.

You can use any tap as a primary as long as you do not apply more than the rated voltage or, draw more current than that winding is rated for.

A step-down transformer makes a perfectly-okay step up transformer. It won't care.

600 volts powers 30 to 40 watt plate sweep tubes.

Id venture a guess of gold to folks like us, probably scrap price to the average Joe (assuming copper, and not copper-clad alum windings).
