I do have a scope (recapped), but have never used it and do not know how to use it. Something I plan on getting to soon (NOW may be the time).
Got an RCA WO-33A, with original funky looking probe.

Thanks for your suggestions. I already substituted the damper, horiz osc and horiz output tubes and fired it up and it gave me same condition. No raster, no horiz osc noise at all and red-plating 6CD6. Also tested every other tube in power chassis and all seem ok. But I substituted out these three with others I had and got the same condition. Set was worked fine for about 3 weeks after recap, estimate - put about 15 hours on it. Like I said the Horiz was never quite right. Seems like the whine of the osc was a bit louder than my other sets. It was stable but not perfectly symmetrical. Would be elongated to the left or to the right, could never get it centered, where it did not look out of whack one way or the other. Almost like it would drift out over time.
