If you get some grid current, either the amplifier is unstable (unlikely) or a tube is going bad.

The Titan 425 can easily be run with one tube at a time to zero in on something like this. Just be careful with discharge of the high voltage as you go in. For quick tests, you don't need to replace all the cover screws, only enough that the interlock makes contact.
