^ japetus - are you referring to his other thread potentially in our 'Thread for fallen members' subforum? Either way, I directed him here as I figured it would get the most exposure. I'm going to guess that he/she does not speak fluent English.
@Discardedvinyl76 - what exactly happened and how do you know it is a transformer?
Whatever it was, my first place to look and troubleshoot is the tubes (power, then phase inverter, then preamp)
