Report Review for product Vacuum Tube - 5Y3 S, JJ Electronics, Rectifier

You are reporting the following product review:

The JJ 5Y3 seems to be a really well constructed current production tube. Unlike the Sovtek, which has a sleeved heater, the JJ is the traditional style. While has a higher forward voltage drop than the Sovtek, some older equipment cannot handle the higher B+ of the Sovtek. I really like this JJ tube.
