Hello Everyone,
I'm new to this forum but I think I've brought a neat find that I'd like to share in hopes of getting some information back! I was lucky enough to stumble upon an RCA 21-CD-8865U "Anderson" with a CTC-7D chassis at a local estate this week. The elderly couple had a collection of DVD's larger than most people could hope to amass in a lifetime. Obviously they got hooked on television early with this color RCA.
Let me start off by saying that I know little about vintage TV's but I've been collecting antique radios since 1996. I've been meaning to get a vintage TV up and running before '09 and when I saw this one was an early color set, I couldn't resist!
After looking over the set, I've found some good and some bad.
The good: besides one ding in the front, the cabinet is in pretty good shape. Also, the tube, which is a 21CYP22A LF12312 looks very clean with no noticeable irregularities in the phosphors. Being that the neck is stamped with the RCA Colorama logo I wonder if it was replaced at one time. Furthermore, the chassis is very clean and besides some dust it doesn't look like it's ever seen any repairs. The serial is B8160291 and the chassis is stamped with CTC7D, 7451L1, RVP 274.
Now for the bad: someone clipped another fuse over the original fuse on the chassis, which is blown. To make matters worse, there are some drips of wax coming out of the top of the power transformer. While I haven't cleaned up the chassis or checked any of the tubes, I'm hoping that this problem is nothing more than some short and bad tubes... which is probably what sent this set into the basement in the first place. The flyback looks okay and I see no other damage... but the sky is the limit with TV problems... hence why I rarely work on them.
Which brings me to the part where I ask for some help: when exactly was this set made and how can I go about finding schematics? I see someone posted CTC-7 schematic downloads on this forum some years back but the link is now dead. Does anybody have a copy they could send me? Without schematics I think I am pretty much lost. Thanks in advance!
