I am sorry to hear that. Maybe something minor that can be repaired, hopefully. I haven't run my Aerco in quite some time, but, honestly, I will never sell it. Jerry made it for me and it is a bonafide piece of taper history. Probably the only piece of gear I own that I wouldn't part with (it would need to be pretty dire before I ditched the 4015s, though).
Fingers crossed for you!
