The image on the CRT looks good, although it's a little hard to judge when peering in at such an angle. Of course, the smaller the CRT, the sharper things look, too. If I remove the side plates from the optics box, I should be able to inspect the mirrors more closely.
On another note, has anyone ever seen patent documents for the Norelco Protelgram unit? I assume it was patented somewhere, although a quick search of US patents didn't turn up anything.
