That was quick!!!!! "The 5E3 circuit is still intact except for 3 things: 1. SS rectification, lessens the flubbing out typical in a standard Deluxe 2. Coupling cap size lowered a hair to again prevent bass flubbing 3. Much better output transformer, just gives it a more solid, big sound. Will have to get clips up one of these days, maybe just with my iphone. Thanks - RandyF"
