I know you meant 500VA or .5KVA. I've made that same error.
haha, I'm always specifying 500kVA transformers at work, I didn't even catch that

So far I ran the CRT for 8 hours at 6.3V, and I also tried running it for 30 minutes at 8V. At 8V, emission is well into "good" (75/100 on the B&K 466), but at 6.3V, it's at the high end of the bad scale.

Even after letting it sit all night long at 6.3V, it's still reading bad. Cutoff only occurs if I turn down G1 to a bit less than 40V.

I think this tube will make a picture, but do you think it's realistic it will wake up more than this? I've had them come to life before, but this isn't looking good to me. Then again, I haven't done as many as most people here.
