Your chassis dimensions: 17"W x 8"D x 6"H (including Tx and tubes?)
The Woodcraft drawers are made from 5/8" stock. Two sides= 1.25", added to 17.125" (an extra 1/16" on each end for clearance) gives you the width of the cab: 18.375".
Top and bottom= 1.25", added to 7.75" (6 + 1.75 for breathing room) gives you the height of the cab: 9.0"
Cab depth= 8" + 1.5" (in front) + 0.5" (in back) + 0.75" (to remove groove)= 10.75"
So the cab's outside dimensions are: 18.375"W x 10.75"D x 9.0"W.
The drawers are ordered by the outside dimensions, but remember, the cab is a drawer laid on its side. Just think of your empty cab lying on its back.
If you want to have the dovetails on the top of the cab, the width of the cab is the depth of the drawer. Drawer dimensions= 18.375"D x 10.75"H x 9.0"W
If you want the dovetails to be on the ends of the cab, the width of the cab is the width of the front of the drawer. Drawer dimensions= 9.0"D x 10.75"H x 18.375"W
You either have a narrow, deep drawer or a wide, shallow drawer! You'll want to order this drawer, since height is height no matter where you want your dovetails:

The faceplate is listed on some plans as 1/8", but 1/16" is fine, too, and gives you no problems with the knobs and pots. The front can be 1/2" or 3/4". There is a taper in the original from 3/4" to 1/2" on the lower edge.
Attached is a pdf file on plans for a TW cab. It specifies the 3/4" stock Ken Fisher used.
Please check over my calculations to see if everything looks right.
Good Luck :!:

I used a Vox handle, but the neatest idea I have seen is from rj : cutting out holes on both ends just below the top and just wide enough for four fingers.
It leaves the top clear for a wireless or an attenuator.

I'm going to order a flight case for it.

Check distortions' cabs for a hardwood handle cutout that's truly a gem!

Ok, So I had my ceriatone Expession (that was built by nick in full) biased today and pluged it in for the first time and I have to say I really wasnt thrilled, I dont know what is up but it's shrill,noisy, I'm even picking up a Mexican radio station, What's up with that? I was really thinking I was getting a pro rig? has anyone else had any problems like this? If so what are some things I can do to resolve these issue's
Thank's

Take a look inside to see what Nik used for a grid stopper on V1.

The layout shows a 15K.

You could increase that to 33K to try and stop the interference.

My Nik Built Ceriatone Express would quiet down when I touched the chassis and it was microphonic. This wasn't at first. On first fire up the amp sounded great. I have since changed all the tubes, changed the tone caps to .033 and the silver mica cap to 250pf on the board which is going to the treble pot. That helped with the too high treble sound I was getting. Also, I almost forgot, that I changed the shielded wire and input jack that really helped. You don't have to change the jack but I did. The shield wire was bad. I emailed Nik and told him about that as well. The amp at that time were not being built with the snubber resistor 15k. Nik has since added that to his layout. I tried the 15k resistor but took it back out. I also changed the NFB resistor but have gone back to the stock 100k. I still have some ground loop issues but to help with that I retitened all the ground screws and resoldered some.

M Fowler, Ok,
I want to try some of these thing's but I have no idea where these things you are speaking of are, If you can kind of help me out find these and where to get the parts I need to do the mod's like the .033 thing and the silver thing? and where and what to change the input jack wire to? if you have some pic's of these thing's and where they go I know I can figure it out. Thank you so much! Also where are these ground screws?

What would be causing the radio station (if that is even what it is) to be coming through my speakers? I am still waiting on my head box so right noe it is sitting on my 2x12 bogner cab with a piece of card board under it and then a piece of tin foil in hopes to get it to stop but to no avail.

The radio station is probably due to bad guitar cable, bad guitar wiring. or ground loop in the amp. Try different cables and different guitars first.

For the other stuff, I need to know if you have worked on high voltage tube amps before, because I do not want you getting hurt my friend. Email me anytime you want.
