Thanks a lot Rick, I fiddled with it for an hour..

Overall, it seems to be working fine. I brought it up slowly on my variac, over the course of an hour. At full line voltage (120 RMS), it's drawing about 300mA - this seems good to me. Aluminum parts of the case are a little spotty, but that should clean up.. maybe a little Nev-r-dull? The rest cleaned up fine with a rag and some 409.

I do hear a little whine from the CRT's oscillator(s), is that anything to be concerned about?

Lastly, the blue plastic screen is cracked in two. Any suggestions for a replacement? Seems like generic blue plexi to me.

Thanks again!!

Bill
