Those numbers, unfortunately, don't help us. Probably serial numbers. Really, the tube is likely to either be either a 23V or 25V, and either one will substitute for a long list of tubes. If I had to go out on a limb I would say it is the 23V. Could be like a 25XP22, 25AP22, something like that. Well worth saving as the supply is slowly drying up.
