I've taken on a comission to build an amp that is based on the 5E3, but... of increased power, while keeping things more or less in line with the 5E3 tone as much as possible. Worked out using a Hammond 660vCT at 140ma for the power supply. And use a pair of coke bottle KT66's I've got here. Output... a Tremolux replacement. No choke. Switchable fixed or cathode bias. Gonna beef up the filtration just a little. Not much. I'm hoping the 140ish ma and KT66's will sag about as much as 90ma and 6V6's. We'll see. Which brings me to the rectifier... something tells me he's gonna like the sound of the 5Y3 - right before it blows. Dunno, maybe it'll hold up. Can't talk him out of a modern Jensen... sigh. Maybe it will offset the low end being a bit tighter than a Deluxe. C12N is his choice. I'd have gone with something else. Dunno what exactly, but I'm rather fond of oversized Celestions in tweeds, but that's just me. I guess its a personal thing, but I find the modern Jensens about as pleasing as a bad Tele bridge pickup.... So, hoping to get about 35watts. Its going into a seafoam green wide panel cabinet with some nice small checker grille cloth. I'll post a few pics as it goes together. Probably this weekend I'll have time to get some serious work on it.
