Here are some pictures of the results of the restoration. The convergence is certainly a compromise. The multiburst shows video response through 3 MHz with 3.58 filtered out and maybe just a little at 4 MHz. I added a 22 uH choke in the screen circuit of the video output pentode patterned after a later Zenith set with a peaking adjustment.
