I rebuilt my Scott 296 a few months back and finally got time to finish the rebuild of my Scott 355 pre/tuner. I'm using the 355 as a stand alone tuner as it has the large "G" chassis like the 296. When finished, one thing that was really annoying is the way the tuning meter on the 355 bounces around and then settles every time a station is tuned. Not just a small bounce, the crazy thing goes all over the place and takes time to settle. I had noticed this on a Scott tuner I used to own, and I'm sure it's from Scott's use of cheap meters.
I knew a capacitor parallel with the meter could possibly help the problem as I've seen this done on other meters. After trying quite a few values I found a 1000uf cap tacked on the rear of the meter removed 95% of the bounce, yet still allowed accurate tuning of the stations. I used a 1000uf @ 50V but a 50V cap is not needed, just what I had on hand. You need to watch polarity of the capacitor keeping it the same as the meter.
I'm thinking this would work on any of the other Scott tuners as well so I thought I'd post my results.
