None of the test results are altered, we care about our reputation and integrity.

I do combine shipping so if buying more tubes wait for the invoice to save on shipping. 

All of the tubes were tested on a calibrated Sencore TC-162 tester, one of the best for detecting Shorts and Leaks

and also tubes were checked on a calibrated Britain AVO MARKIII tube tester,one of the best for emission test.

Excellent cosmetic and working condition.

Take a good look at the pictures as they give a much better description than words can.
