Is it ok to use a very old preamp tube?

I'm currently using an ancient mullard 12at7. Is there any danger in keeping this tube in there? It's original in my 1964 super reverb, sounds great.

No problem. I am using several preamp tubes from before 1953.

I have all NOS or 'pulls' preamp tubes in all four of my amps, most from the 50's and early 60's. Can't image not using them.

Old Tubes are cool,

I am curently breadboarding/building a .75-1W SE guitar amp using a fine specimen from my collection of tubes from the 20's

NEVER! It is not safe! You should take all of your old tubes out & send them to me! :D
...so I can add them to the old tubes that I use in my amps!:AOK

I'll post pictures and the schematic down the road,

Think that CX-310 is sexy? You should see the mess plate rectifier lit up;)

I'd rather have a dozen old preamp tubes of unknown usage and origin than a hundred new current production preamp tubes.
