"...and the smoke it encircled his head like a wreath..." - no, not Santa, but me, wondering what that smell is - something died suddenly in the tuner (although I didn't realize it for a few seconds, because I was working on adjusting the chroma oscillator, and thought at first I killed that) but it turned out to be the B+ dropping resistor on the tuner. Now I'll have to track that down. The burned resistor is supposed to be 1k/2W, now measures 270 ohms. A secondary dropping resistor that should measure 6k (6.8k in parallel with 56k) now measures 1k in the circuit - I haven't figured out where the parallel path is, if any. But all the B+ points measure about 2M to ground, which they should - no shorts evident!

That's enough geeking around for Christmas Eve - heading for some eggnog and carols on TV - Merry Christmas all.

Oh - and thanks to Brian for the tube shields - just the assortment I needed.
