Hi With any Rb, the first question is if the ovens are running and cutting back properly. There *should* be some sort of oven monitor settings on the switch. It’s a reasonable bet that < 1 hr is needed to get them to cut back. The gotcha is that if they don’t cut back you start to fry components.
Past that, the OCXO likely is a bit off frequency after many decades. Getting it tuned close to 5 MHz is a good next step. Past that, this is a big old 5065 sized beast, there’s a lot in it that could go wrong. Bottom line - you very much need a manual.
