Hi guys,
I've been working on this 5E3 amp for the past couple of weeks. I built this one for http://leeroystagger.com/ (http://leeroystagger.com/)
It's simply a 5E3 in a tweed Pro style cabinet. Mojo built the awesome lacquered cabinet. I sure love their cabs. Highly recommended.
The cool thang about this project was to hear how a cabinet can affect the tone. My customer wanted the 5e3 tone with just a little more oomph. I think we succeeded in doing just that. This cab has a baffle cut for a 15" and then uses a baffle converter to step it down to 12". Makes it nice and a little more versatile.
I've installed a mullard reissue 12ax7 in v1 position, jj 12ax7 in v2 position and JJ 6V6's for power and a 5Y3S rectifier.
Speaker is a Weber Alnico 12a125a, 30W, light doping.
Another fun project!

Oh, it sure makes a difference!!
I used to own a '55 Tremolux. The circuit is essentially a 5E3, with a tremolo circuit and a paraphase inverter to facilitate trem injection.
It's not fair to compare a '55 with a modern copy, but the Tremoloux was bigger, swampier and cooler than my modern 5E3 copy. My 5E3 uses a fairly authentic, smaller narrow panel cabinet. It captures about 90% of the '55's mojo.
