Hey Guys on tour right now, and our bassist's Traynor Custom Special YBA-3 is having an issue basically 2 of the EL34 power tubes plates are glowing red like crazy and then the circuit breaker is shutting the amp down. originally it was one tube, and then when we installed new jjel34's two of them are glowing red on the plates. what would be causing this? and how could we fix it? we've got access to a soldering gun, a DMM and not much else! hah! please help!
