Emax

Thank you for allowing me to enter into your group of all things Emax.
You will have to excuse my lack of techy-ness and naivety regarding 
these wonderful machines, as it's the first time I've ever owned one, 
although I have had access to one before and I loved the sounds from it.
I have a few questions which I hope you can help me with (and for which 
I'd be very grateful), having just been given my Emax...the original 
one, not Emax2.

1. Everytime I switch my Emax on, it's blowing the glass fuse at the 
back of the lead.....What next???
2. Where do I get banks from...disks don't appear to be available 
anymore, and I have no idea what I need to do to get stuff onto disk, 
or what disks to use...where to buy etc etc....(Again -  sorry for my 
ignorance)
3. How much does an Emax usually cost these days and If I decide to buy 
this one, how much should I be looking at spending...and is it 
worhwhile??
I hope you can help as I'm a bit lost at the minute.....
Many Thanks for help.
