Definitly check riders to confirm. I've had Sam's typeos F^ck me up on part values and locations twice now! When in doubt check other sources.

Mmm-hmm.


How much you wanna bet those tards at Sams fat fingered a 1 in before 3.5 and ended up printing 13.5 instead? I can almost see it happening, and it makes sense since the one I have here reads the same 3.5 ohms as Kevin's does. Hmm, maybe the yoke isn't to blame for my horizontal troubles after all?


Since we're on the subject, I was trying to get some work done to the 21CT55 the other day, using the assistance of my RCA service guide. It's having issues with noise in the picture, so I was attempting to trace it back to it's source in the schematic. I got to a point where I was searching the 1st video and chroma bandpass amp tube circuits, and realized that the schematic showed the grid of the chroma amp tube going to the contrast control wiper. Mmkay, here's pin 8 on the chassis, follow wire back to.... the color control?!? WTF!!! Scratch head, consult Sams... Sure as sh!t, the RCA book has a damn CT-100 schematic labeled as a CTC-2B!

So it's not just Sams, I guess. I'll have to apply my car salesman mantra of "no trust" to schematics as well, since I have yet to find one that exactly matches ANY chassis I currently own.

Pretty frustrating. Good thing we're only in it for the hobby.
