Title: Upgrading the Choke? Post by: Steven_nl on December 15, 2008, 08:32:44 AM Hi Guys
I read a post on the amp garage forum about changing the Choke of the OTS. "The Ceriatone choke - seen on the photo below - just does have a DC resistance of 30 ohms and an inductivity of about 1.5H - after I've swapped in a Fender choke (022699) w/ a DC resistance of ~100 ohms and an inductivity of about 4H the amp's sound has been much more organic, smoother - the previous rawness almost was gone." What do you think? Would it be worthwhile? Title: Re: Upgrading the Choke? Post by: bluegate on December 15, 2008, 10:21:45 AM Hi Steven,
It's a relative cheap and easy mod. The choke has two wires, that's it... Dave Title: Re: Upgrading the Choke? Post by: Steven_nl on December 15, 2008, 10:33:02 AM Hi Dave. Yeah looks easy enough (although I keep away from soldering irons myself) but will it make a difference?

;) ...but if you do change it, do let us know what happened. ;D Title: Re: Upgrading the Choke? Post by: bluegate on December 16, 2008, 08:30:13 AM The choke tries to keep the voltage/current up when you hit the poweramp hard.
Because its a coil, it will resist changes by fighting it with induction. Can't tell you what it'll do sonically... Title: Re: Upgrading the Choke? Post by: ic-racer on December 22, 2008, 03:50:01 PM I built my 100w version with an 022699. Looks like Mr.D also used that one in 50W amps like #40.
