No Sharp Points?
First, regarding the feed-though cap: When I say "destroyed," I mean it. Fortunately, I studied sweep alignment for two years at the Sorbonne. Unfortunately, this is not a French television set. But seriously, there's no need to despair. I want to get rid of this set as soon as I'm finished playing with it. The only way I can fail is by not doing anything at all. So, the project proceeds regardless of the outcome.
No Sharp Points? I have a healthy degree of anxiety about high voltages. Somewhere in the Sams and Rider information there's a note to avoid sharp points in solder joints on high voltage lines. I'm not sure why, but I copied the original bulky, rounded connection to the base of the HV rectifier. What might happen if there was a sharp point? I also made the high voltage cable a foot longer (temporary) with plenty of insulation at the connection. ![]() I envisioned a wooden cradle to keep the CRT securely positioned, but I found a more practical option. ![]() I found one glitch in the tuner (besides the feed-through cap). There's no connection to the plate of the 6BC5. The circuit is open somewhere in the area shown below. ![]() I was getting inconsistent resistance readings in this circuit for days until I found one defective solder joint. After repairing it, there was still no connection to the coil or 110V line. ![]() The open circuit must be between the two left contact strips in the picture, but the coil and connection are neither accessible nor visible. ![]() It looks to me that if I can remove the single rivet, that the yellow plastic mount will slide off of the contact strips, and I'll have access to whatever is hiding behind it. Before I attempt this, does anyone have a better suggestion? Thanks, Henry "The Destroyer of Caps."
