Hello folks, just need a little experience here, I was going to replace the far right lamp on the radio dial that had a burnt out lamp in my daughters old Rotel RX454 integrated amplifier and use one I already had here which was a F8 250 8 V white lamp,ones I had used for my Marantz Integated amps.
The other dial lamps were working before I started this repair. Once installed the entire front series of lamps is now not working,are they like an old string set of Japanese Christmas lights that all need to be the same bulb, functioning in order to work?
The bulbs that are in there currently have a bull nose on them, and are slightly longer ,as appose to a flat end, not sure if that's an issue? See Photo attached.
I've enclosed the service manual page that indicates what bulbs should be used? Is there anything I'm missing here?

Much Appreciated

They are in parallel on dedicated transformer secondary.
