Title: It lives!! Post by: Cobra on November 29, 2008, 01:59:42 PM It's alive!! It's alive!!
The Cobraluxe 5e3 head... (http://www.tdpri.com/telephoto/data/539/cobraluxe_1_2_.jpg) These projects just seem to take forever! Of course it's modded, just a little... Split cathodes on V1 with different voicings, switchable fixed/cathode bias w/test points & bias pot on the back panel, Brimar power, Bendix 5y3 recto, screen resistors, & BIG IRON! (http://i23.photobucket.com/albums/b378/lazcabanas/BigIronTattoo-1.jpg) ;D :o Cleen to scream!! I guess for the truly traditional, it's not really a 5e3 anymore, but I'm cool with it! It's sounding really good, although one of the speakers in the 2x12 (pic below) is new, & needs to be pounded for awhile to break in. It's a little hard, strident, & spikey right now. I'm on it! The mic channel (split cathode) is basically what the inst channel is on the original, & voiced so it's still very traditional & vintage sounding. The other split cathode channel is voiced more modern and british, & here's where the clean to scream thing with the guitar volume really happens, a huge plus! It's tighter & punchier, with a little more headroom, not so smeared and flabby in the lows, & it's got better range on the volume dials. In fixed bias mode it tightens up even more, sorta like a BF Deluxe, without the mid scoop & the farty lows. It's more dynamic & touch sensitive. The cleans seem better than a stock 5e3, & easier to dial in. The grindy OD tones are totally cool, with a sort of harder revved up british flavor. It's kinda like a southern rockabilly redneck that lives in Ipswich, & likes to have tea every day at the same time!

Great looking amp! I'm just starting a 5E3 build(my first) and I'm interested in the split cathode mod. Now that the "honeymoon phase" is over, would you still recommend it? What cap values did you use on each channel? Thanks in advance, Gerry P.S. how about some gut shot pics? Title: Re: It lives!! Post by: cmoore on January 25, 2009, 03:13:07 AM Good Heavens that is a nice looking head!!! Is there a big advantage to adding screen resistors? I changed my bias resistor from 250 to 470 and that brought the MA's down from about 41 to 27.
Thank You post script em - I would like to request some gut shots also please. |
