Any ideas why?
I opened the guy up and there seems to be nothing obvious that is broken inside so maybe a transformer or maybe just the tubes...?
Maybe even the preamp! don't know.
The tubes may also be in the wrong places. Finally how do you know which tube goes where!?
...or are the assign a certain slot after being biased with the amp?
I'm going to buy new ones, where and how should i purchase them?
They need to be "Matched" to work correctly right and do i need to bias the amp for these new tubes?
so if i have all 4 on the right side and only 2 on the left is that okay?and why remove them in pairs?
