power transformer current

[ioginy]

I was given a few power transformers the other day, but have no idea what they were pulled from. I was hoping to use one of them to power a quad of 6L6's but I'm not sure if they can provide enough current. They are pretty hefty chunks of iron and I measured them at 350-0-350. Is there a way to measure their available current?
Thanks.
Cory.

...isn't 350v (unloaded, no less) too low for 6L6GC?

After rectification and filtering, it'll be closer to 430 with a tube and 490 with SS

oh man i just got schooled....and i like it! i dunno what i what i was thinking earlier

How big are they and how much do they weigh , also what is the resistance of the 120 winding and the 350 windings to the center tap .
The lower the resistance of the primay , the more current it can carry .

There used to be a good chart in wiredbecker's post, about halfway down this thread:

Unfortunately, the images seem to be gone. Was anyone wise enough to keep a copy around? The charts had a method to calculate transformer capacity as a function of unit resistance, i.e. ohms per volt. Basically you determine the voltage off the HV secondary, and measure the DC resistance of said winding. Divide one value by the other, then look up the current rating from the chart. The function is a linear one, so if you have two known transfomers you might be able to fudge your own chart.

Edit: Found them... here you go:

Thank you so much. I will give that a whirl as soon as I get home.
