In Germany we have an Shop called Tube Amp Doctor - I shipped in my JMP-1 and they changed the Input Jack, the Data Pot and the Tubes. Fair price and really great repair skills. They also have a very large variety of all kind of tubes and make recommendations for every kind of sound you are looking for.

Trace at Voodoo Amps does the famous JMP-1 modifications, so he knows his way around the circuit and might be able to repair it for you.
