Magnetic shields - for CRT & transformer
 
1 Attachment(s)
Following up a suggestion on another thread here that mag shields could have some further use, perhaps there might be some interest in some parts I've had for many years. As in photo:
1) a two-part shield for CRT, cylindrical part 72mm (2 7/8") diam x 161 (6 3/8"), opening to ~121 (4 13/16") at 89mm axially.
2) Cylindrical 70mm diam x 163 (2 3/4 x 6 7/16") both halves marked 10AB/720
3) Memory claims this was around a transformer in an ancient TV: aperture 75 x 106 (3 x 4 3/16") x 111 (4 3/8") long.
All FOC.

These things can be hard to find, but are essential for good results with electrostatically deflected tubes. I would have thought there would be interest from the television experimenters on the NBTVA Forum.

I guess they're mumetal in which case handle carefully avoiding banging them around as it reduces it's effectiveness as a magnetic shield.
