Nice followup video real nice Happy New Year Bob looking for more great videos in 25 and will be waiting and watching. thanks Mike

Thank you for another great video! I am joining your Patreon. Thank you for showing early tv museum in other vids. My regular work travel takes me aout 5 minutes from there! Cannot wait to visit - Just purchased a membership!

Great to hear! You'll love the museum.

Merry Christmas and a happy new year. Great video thanks

11:21 A little comment on your analysis of R437 68R and R441 100R. The 68R in series with the grid of the output tube is just a grid stopper. The grid itself is high impedance (typ. 470k in circuit as per datasheet) and the grid capacitance is low (as per datasheet 0,8pF). A rise in R437 will not substantially reduce drive as it hardly sees any current flow alas faces no voltage drop across it. However R441 100R feeding the screen grid (not supressor grid as you called it) sees a substantial current draw (around 10mA) and a rise in resistance of R441 from 100R to 175R will cause a higher drop on the screen voltage for a given screen current.

You're right of course. Grid is high impedance. Not sure why I thought that could be an issue back then.

17:51...I remember that the cords on Zenith TV sets was slightly different...

[@bandersentv]

If you mean the early porthole sets, yes. They are polarized and bigger.

[@VioletEuphonium]

I actually just checked on ebay and the seller The Twisted Rose Mercantile is selling TV power cords for only 4 bucks! They're the ones without the ear for the rivets though, just thought I'd let people know here!

[@69Dartman]

I'll remind you... 😉

[@oldradiotvsc9836]

Yes, don't forget to tighten down that IF transformer, looks like sound discriminator coil?

[@FariSamSoli]

is it right that you have made this video 7 years ago, if so too late to tighten down that IF transformer 🤣

[@bandersentv]

Not necessarily. You shall soon see
