I've got an amp that uses parallel OTs. Removing one tube lessens it's output but I wonder what actually happens to the OTs since one remains powered and the other does not.
So with only one powered OT, the secondary is feeding not only the speaker but also the un-powered OT. Both OTs are 8ohm so I am thinking the un-powered one would be seen as an 8ohm like the 8ohm speaker, and this changes the load to 4ohm?
Or even feeding the un-powered OT back to secondary is just plain bad for it?
