Default Re: Baird T5 restoration project.

"Could it be that the earlier tube had a bit of lag built into the phosphor mixture? I've yet to establish the difference between the 15MW1 and 15MW2 crts,"
Hi Andy,
The CRT in the T5 the subject of this discussion is a Cathodevisor 15MW4. A post-war replacement?
I believe the formulation for the white phosphor arrived just in time for the high definition television service in 1936. Even so wasn't the Emiscope 6/1 a green screen tube?

DFWB.
