Mike,

As Chad says, the 6U8A will NOT sub for a 6AU8. However there are the following acceptable swaps for a 6AU8: 6AW8, 6BA8, 6BH8, and if a parallel filament circuit (your case of a scope most likely) also 6CX8, 6EH8, and 6X8/6X8A. Using one of your 6U8As may cause damage to the scope and/or the tube.
