Although this video deals specifically with the conversion of a JW Davis PA amp into a guitar amp, the methods are applicable to the vast majority of such conversions. Since electronic components have become so expensive, conversions like this are the most economic way to obtain a vintage tube guitar amp. All aspects of the conversion are discussed, as well as a review of the circuit, modifications and improvements, and resolution of problems with several of the tubes.
