10KV caps.

The distortion cannot be just the ratio detector because the sound IF in a split sound set changes with the fine tuning.

The distortion is gone. Bad cap in the ratio detector and a couple of cranky tubes. Also eardrummed the audio IF. The sound is nice and clear, no buzz, just a tad low in overall volume. Still, it's usable as is.

Remember it isn't an intercarrier sound set where the sound carrier beats with the video carrier to maintain sound over the video tuning range. In a split sound set you adjust for best sound and the picture should and must be set at that point optimally. The sound tunes like an FM radio and when tuned you accept the video as is. This is why you need the proper equipment to do the alignment.

I have several pieces of equipment and, unfortunately, none work at 24mhz that this old girl uses. I've been thinking of modifying my B&K415 (that I bought new). I aligned a few 44mzh TVs back in the 70s with that genny, and it's easy to use and works well.

I also took my VA48, set it to burst sweep, and fed its video output into a B&K1077B analyst (also bought new) and was able to have it convert the VA48 multiburst signal to 24mhz - the 1077 has an infinitely variable IF output.

I don't have the courage to try this hack setup on the Andrea, although I was considering just connecting it to the IF and scoping the video at the detector and see what the multiburst looks like. I may have something else of no value that I can use that frankensetup to experiment with.

I do have a Precision E-200 for which I only have a couple of crystals, but I don't know how accurate a wobbulator setup is.

Seems to me you are almost there and hope to see you cross the finish line.

Thanks. I planned to finish by the fall, and I'm way ahead of the schedule, so I backed off a bit for other projects.

What I really need to find is some sort of matching mahogany base to put it on.

Thanks for the info.
