Hey there. I wanted to ask a question regarding the diodes that are pictured in the photo I've attached to this post. I read a while back that diodes here would be used to prevent any damage done to the transformer if a power tube were to short or blow. BUT, what I want to know is if there is any possible sonic affects this might have. I've noticed Diodes in the reverse direction have a resistance but I'm not sure if I understand Diodes. Is it possible that the about 1meg of resistance created from the diodes going the opposite direction effects the tone of the amp? any ideas?
