So I got this kit through abraxascabs. Im still thinking whether to get the Mercury Magnetics trannies or not. Right now I'm procuring all needed tools and supplies while I do final planning/ review for the build. This is my first kit build ever except a little amp I did way back in HS. So I might be needing (a lot) help here and there. But I certainly will document pretty much every step of the way to be able to be sure and possibly help others and most importantly have the most fun out of it.

Some photos of sorting the parts. Most will be organized on those plastic containers so I can have an organized work flow and more virtual memory to use on other things while building.;




You can see the nice new metal faceplate here..




I got 200uF yay as all the others now. Nice colors huh?

Grinding the paint out of ground contacts. Pretty much self explanatory.



Did the front controls. After this and testing, I'm much more confident with my first build.







Buss bar was a bit tricky but very satisfying to finish.

Looks like your making good progress.
Thanks for taking the time to document the build.
It will be helpful for others to reference in the future.
Good to see complete pictures of the new chassis.
I see Nik has updated with some new holes. (e.g. LNFB switch)

Good luck and look forward to your build.

Oh are those the holes between the socket holes? I see. I'm well halfway on the build but I gotta get the trannies lol. I have more pics to post.

One quick question, does it matter which 3.15 lead from the power tranny goes to which terminal of the pilot ligh and side of heaters? I mean is it interchangable? Just to be perfectly sure lol.

No, I don't think it matters - it's AC anyway.

Cool pics! Looks like things are moving along. I really like the white chassis - is that a special order, or do they all come that way now?

And you probably know this by now, but Nik is (or at least was a while back) a mercury magnetics dealer - he can get you the dealer price on your trannies and have them ship it direct to you (if you're in the states that is) - great trannies for cheap this way! Send him an email about this.

Hopefully you'll have as good luck with your build as I did - mine worked perfectly at first power up, and still works perfectly!

Hahah well why shouldn't your amp work perfectly. Yes I am a bit nervous for the first power up. Did you check voltages before putting tubes? Or use something like a variac or light bulb device?

Yeah I will probably get the MM from Nik. I have been exchanging emails with him and he's always quick to reply. One of the best things about Ceriatone..

The chassis now comes like that - Metal for more strength and powdercoated cream

No, I just put the tubes in and powered it up, set the bias and went from there. I figured that if there was a problem I could check all the voltages, but it works and sounds fabulous, so I'm happy!

I decided to go ahead and mound the PT. Next up is the OT, then the main boards. The sockets and heaters will be last.

Building an amp is pretty sweet. I like to mount the boards to see what it looks like. Saweet! Anyway I am still to receive my Classic Tone OT and still browsing cabs. I have my G12-65 waiting already.

Thanks man!

I got the 40-18025 from Classic Tone. I'm pretty psyched about it cause its supposedly a "tone monster" Check this demo out;

I trimmed all the wires going from the boards beforehand. I then wires the two boards together then wired the incoming leads to the power board. I wired the board then wired the incoming wires to the main board.. Lastly I wired the main board.


Used the drill method for the heaters and put them hanging on top of the tube sockets.
