The tester that can "listen" to tubes is manufactured by New Sensor (The Sovtek and Electro Harmonix people). It is called the Otto-1.

I have provided a link to the tech specifications and image page.

They are not set up to sell to the general public. If you need help, I have a wholesale account with them.

Natalie, no I do not. I wish I had either the George Kaye or the Otto, but have not set aside the cash to do so.

I know that in spite of testing and listening tests that tubes can become noisy and microphonic hours or days after they have been given a clean bill of health.

I wind up relying on performance in the piece it is going in for the ultimate test. Lots of work to pull and replace until the perfect balance is achieved.
