I guess I'll wipe it off, then. Sure is annoying when you're trying to work on an otherwise clean chassis, wires leaving nasty streaks everywhere and all.


OK, last night I pulled the chassis out to have a closer look at it. There's nothing besides the can caps, and a 2uf/350-volt 'lytic on the video amp board that I can see needs to be replaced. Everything else is either an orange drop, or a brown colored film cap. Did these come with film caps originally, or did someone already do my work for me? They look original to me, they have the same lead covering on them the resistors do.

I had a look at the volume pot, since it was having volume issues. It's a multipurpose thing having a power switch at the back, volume pot in the middle, and color pot in front. Looks like the power switch had been repeatedly slammed to the off position, because the thing had seperated causing intermittent connections on the volume control. I 'rebuilt' it, giving it a good cleaning in the process, now it works as advertized.

I also installed a composite video input jack on the video amp tube's grid, since the tuner is currently dead. This will allow me to work around the tuner, and get the thing at least running.

Put the chassis back in, fired it up. Looks like everything's working, but something's amiss with horizontal hold. I think I might have disturbed something in the circuit, because now the horizontal control is unresponsive. It's definitely getting the signal because it's trying to display a picture, but I can't get horiz to lock to investigate further. I'll look into that more tonight.

Mark: you wouldn't happen to have a small 350-volt 'lytic for the video board, would you?
