RCA CTC4 Seville Restoration

Well, it sounds like your tuner benefitted from cleaning. I love simple solutions.

If you are getting a strong clear picture with good colors, you may be near the declare-victory point. Some bits in old color roundies are better left alone unless you have a very specific reason.

I was one of those folks using rec.antiques.radio+phono 20 years ago, as well. Learned many things from that group, although I drifted away after web-based forums became more active.

"First, do no harm." Yes, although I'd love to learn how to use my Triplet sweep generator better I fear the irreplaceable nature of many of these parts, like I have to tell you Phil . Now with a CTC9 I'll be more game. I will likely however align the tuner to 2016 standards- to work best on Channel 3 At night I wrestle with questions like- if one aligns the tuning for stations which will never exist is it actually aligned? In fact did the alignment even occur?

Need to be more specific on the word "alignment". Sweep alignment of the IF strip is the very last thing to consider. Alignment of the tuner generally amounts to nothing more than setting the local oscillator so the fine tuning control covers the correct range on each channel.

But since the digital-changeover debacle, all the channels are moot except for the one(s) you want to use.
