No documentation beyond the layout provided on the Ceriatone site, not even a schematic.

The turretboard is already populated with the components, the rest you do yourself. But if you don't have any knowledge on amp building, you really need to do a lot more homework before attempting a build. The ladies and gentleman who built amps for Fender, Marshall, etc. in the day, and all the handwired ones today, got extensive training and testing in the do's and don'ts of soldering, lead dress (how to route the wires), order of assembly, etc. and built the amps very much like an assembly line. They didn't need to know anything about how the amp worked, its design, or how to troubleshoot/repair it, that was another department...you don't have that other department if the build goes wrong.

There are tons of blogs and forum posts covering various builds and many companies like Metropolous, Trinity and others have posted step-by-step instructions on many of their amps. Even if they don't cover the EF86 TMB, there information is priceless for learning "best practices." There is also an entire site/forum dedicated to 18-watt Marshall designs, it;s where non-historic circuits like the TMB preamp and the EF86 variant all started....it is www.18watt.com

Not sure where you are...in the U.S., it's usually cheaper to order the Ceriatone without transformers and buy something "local" (Classictone or Mojotone) and save on shipping (and customs) on heavy transformers. The same goes for the cabinet.

Well, you are talking about building the TMB EF86.

That would be this...

So, the original Marshal 18-watt was the Model 1974 (no relation to the year). It had a Normal and Tremolo channel, and realy is it's own amp, not like the large Plexi's at all. These amps were relatively rare, something many people spoke of but few had played (especially in the U.S.), so there was a big trend about a decade ago was to start making clones and then everything exploded with innovation. One of the innovations was to replace the tremolo channel with a Plexi-based preamp with Treble, Middle, Bass controls (dubbed the "TMB"). THe original TMB's used the 1974 Normal channel and the TMB channel, given both the original 18-watt tone and the Plexi-tone. The EF86 replaces the Normal Channel with a preamp more like the late '50's Vox AC15. So, now you have the TMB EF86, which is Vox-esque on one channel and Plexi on the other. This is what you are looking at building.

Some caveats I see...EF86's are very finicky tubes, they go microphonic rather easy...they always have...so you'll want to look into how to isolate the EF86 tube and reduce vibrations. Also, many find the stock TMB channel way too bassy and boomy, so expect this and be ready to research mods to tweak it.

Mercury Magnetics builds good transformers...but their price is disproportionately high. Since you are in Europe, look into options from TAD (Tube Amp Doctor), which is a Europe-based distributor.  There is also IGPW in Germany making beautiful transformers. I am sure there are other options.

Dear Wyatt

I have looked athe the link you have provided for the transformer

on the TAD website I can see two models for the PT

http://www.tubeampdoctor.com/en/shop_Mains_transformers_Mains_Transf_for_Marshall/Mains_transf_for_Marshall_18W_Plexi_TAD_Amp_Kit_955


http://www.tubeampdoctor.com/en/shop_Mains_transformers_Mains_Transf_for_Marshall/Mains_transf_for_Marshall_18W_Plexi_US_version_3265

On the other web site

http://www.ig-transformatoren.com/catalog/en/transformers/mains-transformer/275/igmt-m18tmb?c=48

While for the OT I see the two options

http://www.ig-transformatoren.com/catalog/en/transformers/output-transformers/282/igot-m18r?c=49

http://www.tubeampdoctor.com/en/shop_Output_transformers_Output_Transf_for_Marshall/Output_transf_for_18W_Plexi_Kit_958

I can see some price difference on these, is any beeter than the other?
spec looks similar

The TAD OT has a 9.2k impedence rather than 8k

What you think?

Good job Wyatt on compiling a parts lists.   There are also the potentiometers listed below.

VR1, VR2, VR4    500K ohm, audio taper  (500K-A)
VR3, VR6, VR8    1Meg ohm , audio taper (1M-A)
VR5                    250K ohm, linear taper (250K-L)
VR7                    25K ohm, linear taper (25K-L)

And I put the schematic notation "CCW" near the appropriate pin of each pot for reference.  This means counterclockwise or across the pond anticlockwise position of the pot knob.
