That really is excellent news Cathy. The BT8161 will be so much better with a proper monochrome picture. It will be interesting to see whether the deflection sensitivity is greater for that tube although its reduced length suggests otherwise!

You've no idea how much of a sigh of relief I made when I saw the meter rapidly increase its count, I can tell you!
I have a copy of the manual for the BT9121 which uses the 4603 CRT, and that seems to use a broadly similar scanning circuit to the BT8161.
What I may do is buy one of those £20 (or so) oscilloscope modules from China from eBay and run it up with my x100 probe attached and a battery to power it, so I can happily float the thing up to EHT and look at the deflection plate waveforms directly. At £20, it can be treated as disposable should a flash-over annihilate it!
