Just picked up a rough looking SVT810. Looks rough, all the tolex was cut off and the cab has been painted white(as well as the grill). It sounds brand new and plays perfect. I am looking into getting it restored but don't want to send it off anywhere. So, anyone out there done Amp restoration before? Where can I get tolex? Will an upholstery shop be able to re-tolex it? I want to just find a replacement grill but don't know where to start. Thanks for any help!
