Are these tested for noise & microphonics as part of the price?

We are only able to offer testing on power tubes at this time, but we offer a 10 day no questions asked return policy as well as a 90 day defective item warranty if they do not perform as expected.
I have a McIntoish C220 preamplifier and have to replace 4 12AX7A TUBES. WHICH REPLACEMENT TUBES WOULD YOU RECOMMEND?

Tube selection is subjective by nature and we aren't able to provide recommendations based on the unit they are going in. We advise using the 12AX7 comparison chart to help determine the best 12AX7 for your application.
