Can a leaky or cracked tube harm an amp?

Tubes Asylum

Questions about tubes and gear that glows. FAQ

Hi folks,

I recently received some poorly packed EL84s off of eBay, which resulted in three of the four cracking. There are no obvious signs of damage to the fourth tube; can it be used safely? Is there any risk to the amp from a defective tube, such as a blown transformer, or is the risk limited to the tube itself?

Thank you!!!

A shorted tube can draw too much current and wreck anything in your amp including OPT & PT - Chris O 13:15:25 06/20/07 (4)
