Check out Kendrick amps Pfleugerville ,TX Gerald weber is the owner and usually answers the phone . He actually starts the boutique amp movement in the early 90's by building new "old "'design amps with some tweaks . I have some of his custom builds and am a tube amp guy . Call him send him the chassis or pix and he can give ya an idea you prolly can fix the Tolex or have a local upholsterer fix it . Gerald will be able to tell you if you can fix it and make a buck his work is awsome. Beware the vintage amp market has been soft lately and most guys want origional even if it looks like it was drug down the road by a truck. Good luck pm me if ya need any help Ive been playing for years .
