Reverb feedback?
I have a Sano combo tube amp with a spring reverb. I get a nasty feedback from the reverb. I found that if its (open) back is against a wall I will not get the feedback. What would cause this? How can I fix it? I am woriied about running it with the back covered up because it is poorly ventilated and gets real warm with the back open.  
 
Thanks
