Test Values On 5AR4/ GZ34 Tubes


Do test values matter on these rectifier tubes?

Some sellers on eBay list test values and others just say they test good and when asked say for rectifier tubes the test values don't mean anything.

Any comments appreciated.

Generally speaking when I test a twin diode (rectifier) it's either good or it isn't. Generally the failure mode is as follows: they are usually weak and measure poorly, or they pull too much current and are therefore shorted. Why not just purchase a new GZ-34/5AR4 from a reputable supplier.
