Report Review for product Vacuum Tube - 12AX7A-C5, Ruby Tubes

You are reporting the following product review:

I will say, that after 35 years, and literally thousands of amps modded and made, the chinese tubes are the closest to old smooth plate telefunkens of the new lot...so far, at least.
whoever grades them the best, i guess...
probably worth buying twice as many cheap, and grading em yourself...
