The CTC-16 I did I have limited memory of (it was a fast resto), but on my Silvertone CTC-15 clone (though it might have been old enough for the chassis to be RCA made*) I went slow and learned much...That set worked okay with the maroon drops in it, but many stages especially the color demod/video board benefitted greatly from the replacement of all the maroon drops. If performance seems lacking change those caps. One thing to note with most drop caps most were either plastic film or plastic/paper hybrid dielectric...They may very rarely leak current, but the early hybrid caps have degradation of the paper that will drift the tolerance of the capacitance value well out of tolerance...Most will still pass signal, filter, bypass, create a time constant (or whatever their specific job was) in a passable manner, but will be collctively far enough off optimum to notice.
*Pre 1963 nearly every chassis that was an RCA design used in a smaller brand was RCA made, then sometime in 63 RCA stopped selling chassis to other brands and those brands either built RCA chassis under license or designed their own chassis (some made clones for a while then switched to their own designs).
I rambled too much didn't I...

Not at all! : D I sure love hearing and learning about all about this stuff
I will check on the cans and see if they get warm at all. Probably get the drops changed out and check on that horizontal
