Title: New 2550 project starting Post by: T Wilcox on April 25, 2011, 04:08:24 PM Hello all
Been a little boring around here on the british side of the forum, so I went ahead and ordered a 2550 kit #1 from Nik and will try and document this build as best as I can since there is not alot of posts on this amp! So far I have the 2550 pack#1 kit hopefully shipping this week. Ordered OT and PT from Magnetic components PT = Plexi45/50 watt part# 40-18054 OT = Jcm 800/Jmp50 part# 40-18025 Choke = 10henry choke from Mercury Magnetics. I have not purchased tubes yet and would like to hear any recommendations from current 2550/2555/2203/2204 owners if they are out there. Will start posting pics and stuff once all parts arrive!

We await your progress. :) Title: Re: New 2550 project starting Post by: T Wilcox on April 27, 2011, 02:10:24 PM Still waiting to hear when it will ship!
Got the choke already and the OT & PT are in transit. So Nik if your reading this, Hurry up and ship ;D Thanks for posting those settings! I am a fan of JB! I had never even heard of a dumble until I read his dual amp tone recipe on the JB forum, and his tone has inspired me to get the Jube as well! If I had all the gear he had I still wouldnt sound like him though. The only amp I could see myself needing after this is maybe a Yeti or Chupacabra so I can get the metal tone. I am hoping Nik makes them as kits in the future. He said maybe! Todd Title: Re: New 2550 project starting Post by: T Wilcox on May 06, 2011, 04:02:52 PM OK
Got the kit on tuesday 5-3-11 Here we go. If anyone see's any errors please inform me. I have a lot of pics to load so I will try to get as many uploaded now but may have to get back to it later! Todd Wilcox Title: Re: New 2550 project starting Post by: T Wilcox on May 06, 2011, 04:09:53 PM Day 1

Title: Re: New 2550 project starting Post by: T Wilcox on May 06, 2011, 04:46:47 PM OK I think that's it!
I still have a little tidying up to do! I ended up getting a pair of matched SED =C= EL-34's Will use JJ 12ax7's until I can get some better pre's Most of the solid wire you see inside the amp is 18AWG solid that I reaped from lighting ballast's ( It's easier for me to work with ). If anyone has any questions or suggestions please speak up! Thanks Todd Title: Re: New 2550 project starting Post by: SoundPerf on May 06, 2011, 06:02:15 PM Looking good!!! :chairdance:
Really nice build. Title: Re: New 2550 project starting Post by: T Wilcox on May 06, 2011, 06:46:49 PM Would still be trying to figure out the PT wiring if it weren't for you Soundperf!
So double thank you! Todd Title: Re: New 2550 project starting Post by: plasticvonaband on May 06, 2011, 07:58:23 PM very nice!!!
Title: Re: New 2550 project starting Post by: T Wilcox on May 06, 2011, 08:10:35 PM Thank you Plasticvonaband, I appreciate the compliment!
Now the only trick will be to power up without letting the smoke out of the components:) Todd Title: Re: New 2550 project starting Post by: cmoore on May 06, 2011, 09:17:23 PM Nice Job!
Thanks for taking the time to document all of this. I wonder where Nik gets those 600 Volt caps from.? Title: Re: New 2550 project starting Post by: T Wilcox on May 07, 2011, 09:43:25 PM Nice Job! Thanks I appreciate the compliment.Thanks for taking the time to document all of this. I wonder where Nik gets those 600 Volt caps from.? As far as documenting it , no problem at all just took a few pics really Im not sure the caps but I bet he'd be willing to help you get some if you need'em Todd Title: Re: New 2550 project starting Post by: T Wilcox on May 07, 2011, 09:51:25 PM How does it sound? :) It sounds great!!!Had a wiring problem with the OT primary and had to de-solder and swap primaries. I've heard builders experience this often, it made a crazy as sound when wired wrong! But since I got that fixed early this morning Ive put about 4 hrs on the amp so far. I have tried the settings you recommended and WOW. I Likeee ;D It will definitely compliment the ODS I have. Just gotta get a good ABY now! Todd Title: Re: New 2550 project starting Post by: T Wilcox on May 09, 2011, 03:19:00 AM Cant really compare the SED's with anything yet!
Only other amp I have with El34's is the JSX and they are crappy GT's that really need to be replaced but thats another project! I have been tuberollin with the OTS and so far am liking the NOS stuff. I wont know about the SED'd really until I get some proper 12ax7s pushin em. This amp drips frickin Rock and Roll. It's got that Low end Thunk that Marshalls are known for! Todd Title: Re: New 2550 project starting Post by: T Wilcox on June 09, 2011, 03:46:51 PM Here is 2550 in the headcab
