RCA 9TC240 Alignment...The start of my education (I hope!)

[Chris K]

Hi all. I wanna thank everyone for their help on the long thread that helped me sort out power, sound, re-wiring et al on this TV. I now have a good picture with very good resolution and sound coming out of a speaker. I'd like to learn something about alignments, fed signals, scope traces, sweep and the like. I thought I would start simple with the discriminator and sound IF alignment. Below is the instruction section in the Rider's service manual for this:



...and some traces and transformer location figures





For those who have participated in helpful discussions before, you probably know what my level of experience is. I can talk some of the talk but there are some significant gaps there. I usually get over my embarrassment fairly quickly but please, be gentle!!!

Over the next few days, I hope to move through the VTVM and scope trace steps in this protocol. Ten fifteen pm on the east coast so tomorrow evening I'll begin. I have done a couple of min/max adjustments using the VTVM before so hopefully, I'll get off to a good start! TIA for the help!
