Revisiting an old topic - Adding DC Restoration to a 1950s TV

[Kevin Kuehn]

Don't get me wrong, I'm not suggesting the DC restorer isn't helping out on your Marconi. I was simply pointing out that there's a multitude of things than can compound the situation. I've watched modern over the air TV from the S video luminance output, through my Blonder Tongue agile modulator, which even then the contrast can seem very washed out, and this on a set with DC coupling from detector to CRT. It's not solely a mater of DC component. [edit] well it might be a matter of DC component gone missing from some point in the signal chain, but not necessarily within the vintage TV.

I'm not thinking it is a miracle solution, but rather a situation where every little bit helps. The Marconi is never going to perform like something newer, but if three little $0.10 parts can make it 10% better then why not? The elephant in the room with the Marconi is that the CRT is on the weak side, which already diminishes the contrast range. Which reminds me I ought to get my blonder tongue modulator up and running!
