I used Weber's layout, although truly between ceriatone, weber and those available at 18watt.com theres not much difference, slight differences but not huge. That might be pretty cool using Sluckey's preamp on a el84 output depends on if you like el84's or not. The tmb18 cops the mid-range sound of the Marshall and combines it with some chime that I really like not unlike a Vox. It might also be cool to use a EF86 or maybe the 5879 the guys are using in the Hoso56 here too, if you like that sort of grind. I play mainly rhythm in our band, but do get my lead chops in and these little el84 amps really cut through pretty well for what I do.

My power section is a tad different because my cap can was only 2 sections, so I just added another 22 uf which I glued to the bottom of the chassis just to get a bit more filtering. It looks something like 32-32-22 now and I use the copper cap as a replacement for the ez81 (which amounts to a 61 ohm 10 watt resistor and two big diodes I know because I've had it apart :D ). I'm using a 270fx hammond and deluxe reverb OT which seems to work real good, nothings getting hot so I guess I did something right for a change. :D
