The Dr.Tube JCM2000 Stable Bias Kit solves the problem of the drifting bias in the Marshall JCM2000 DSL50, DSL100, TSL100 and TSL122 amps. This kit is not suited for the TSL60 amps! See Dr.Tube JCM2000 Stable Bias Mod for detailed information on this matter.
This kit is supplied unassembled with all the parts (and installation instructions) needed to assemble either the DSL or the TSL version. This means that you will have some parts left over when you are finished.
This kit can also be installed as a complete modification by Dr.Tube. Obviously this cannot be ordered through the Online Store but the costs for this modification are € 130,00.
Don’t forget to order the handy hollow drill.
