Accidentally ran 2A3 tubes at 5V?

[Blues!]

I have a pair of EH 2A3 GG tubes for a Vinnie Rossi Lio. I used them for about 5 hours on 5V instead of 2.5V. What are the chances they are not damaged? Thanks

It’s possible you caused some degradation to cathode life, but the tubes should be fine to use.

Unless you have golden ears you will not hear a thing.

But you wouldn't be using 2A3 tubes if you didn't have golden ears!
