A little over a year ago I was working on my RCA CTC5 Aldrich and was having a heck of a time with the brightness and contrast controls. They seemed to interact with each other and neither worked as you would expect it should. bgadow (Bryan) came up with an article discussing a factory modification to correct this problem. I performed the fairly simple modification and presto....the brightness and contrast worked 100% normal. Yes...it improved the picture greatly!!

I don't know what the RCA engineers were thinking when they designed the set? It just didn't work right. But with the modification all is well.

Perhaps they were thinking....

Let's see, how can we get the price below $ 500....cut wideband I demodulation......cheapen the cabinet...Hmmm, electrolytics aint cheap, any way we can get that one out of the contrast circuit???

I wonder of this omission was common to all CTC-5s, just the less expensive "Super" models, or unique to the least-expensive Aldrich
