Well it is complete. The latest cookie tin amp - an 18W Marshall in a Jack Daniels tin.
These cookie tin amps are meant to be a piece of artwork - useful artwork but art nonetheless.
I intend to sell this one. The only possible addition will be a small brass nameplate on the front and maybe another on the back with a serial number. If I manage to sell it I will use that money to build another and so on and so on. I have no interest in becoming an amp manufacturer but selling my art seems to be a fine way to go.

This is a faithful replica of the normal channel of a model 1974 Marshall from the late 60's. I didn't bother with the tremelo channel because well, who uses tremelo these days? Also it's in a cookie tin, there aint much room.
The only deviation from stock was the addition of a bit more capacitance in the power supply. The originals were sorely lacking in that department. The extra capacitance tamed the mains hum nicely, it's quite quiet now.
Well you want to see pics don't you?






I am running JJ EL84's and NOS valves elsewhere (currently an American Raytheon 12AX7, an Australian Miniwatt 12AX7 which is basically a Mulard and an Adzam rectifier)
Classic Tone transformers from Chicago
F&T filter caps
Sprague Atom cathode caps
Mallory signal caps
CTS pots

The box is reinforced with 2mm aluminium top, front and back. The sides with 3mm aluminium.
Gold plated tube socket retainers on all but the ones with the black shields.
Ceramic sockets with gold connectors
The turret board is one I made myself.
Brass handles.

Now I know you lot want a gutshot so here it is:


So what does it sound like I hear you ask? It sounds like an old Marshall. I am running it through a boutique greenback clone and it sounds freakin awesom. Just like an 18W Marshall should.
Crank it and it gets real Beano'ish. It's a mini Plexi. Back off the throttle a bit and you get those lovely JTM-like cleans we all love. This is one seriously good blues amp.

And so a family shot:


They're getting bigger each generation huh?

Erm, I'm more than just a little n00b when it comes to electronics... but are the caps on the JD amp exposed?

Exposed where? The cans are sticking out the top but that's no problem.

The blue things between your output transformer and power transformer?

Nice heterochromatic effect on the cat's eyes btw.

caps are "exposed" in a way but the electrical parts aren't exposed so the user is safe.


i think the filter caps are just fine as long as you bypass all cathodes completely and use big enough coupling caps to feed the bass through. distorted bass notes is what marshalls are all about!

Adding 16uF to each rung of the filter did wonders. It made it noticeably quieter on the hum front.

And yes kitty, the bitey part of the cap is inside the tin, safely away from the user.
That is how the cats eyes actually are. The blue one tends to catch the flash more and get red-eye. Always does that.

Yeah, next time I'm going to go for something a bit lighter. Probably 1.5mm. 2mm was too thick for my nibbler.
We don't have aluminum here (in a country that actually produces the stuff) we have aluminium.

I'm asking Au$650 plus postage. It cost over $350 in parts. Quite a bit more I think. And as you can imagine, there's a lot of time involved to build something like this. Lots harder to build an amp in a tin than a normal chassis.
Go to my website (link in sig) if you are interested. You'll see an amp button in the top right. Just follow your nose.

Oh, and I can connect it up for 120V too if I need to. It's currently on 240V but the tap is there for 120V.

Ah so that's what you mean by amps that are art.

True art has no other purpose than itself you know

I kid, its really clean, looks very simple too (I know that it isn't necessarily so though). Love the 18w Marshalls.

Nice work mate
#14
Well I'm not hoping to make a living out of these things, I just want to be able to make enough to keep doing it - and get a little pocket money along the way to help finance some other things. I have a JTM45 chassis that needs populating. A couple of hundred would go towards that.
I'm not greedy.

I just weighed it. It weighs 5.2 kg (11.5 lb)

Thanks guys.
Sorry I don't have any recording gear going. Been too busy building amps and playing them. If I get something working I'll put some up. But you all know what an old Marshall sounds like, surely.

Ben, I could send it via surface mail to the States for about Au$70 and by express courier for about Au$180. I'd have to add the cost of the box to pack it in too but that can't cost very much.

Srsly that's awesome cath.

O and I found an old mint tin in the garage, can you make me a hardwired Amplug clone?
#22
That is really sweet Cathbard. But if you want to go with the work of art idea, which I agree with, you would really benefit from finding a way to hide those filter caps. They are totally out of place visually.
#23
Handwired Amplug.

There's not a lot of room in there fly, that's why I went for chassis mounted caps. Black ones would have been nice but F&T are blue. Maybe next time I'll use Sprague Atoms, they're black.

I'll have to put the Classic T models on my to-try list. Shame the finish options there are Anachronism Gold, Nuclear Waste and Aged Clown, because in principle the plaintop is right up my alley.

Yeah, I was thinking that black would make a big difference.

old school caps were grounded on their canisters so there was a little safety hazard with them.

new caps don't do that for the most part.

there are can capacitor covers so it's not a big deal visually.

Thanks guys.
I did try to get brass capacitor clamps but I couldn't find any. Where did you find those covers, Min?
As for the old grounded cap cans, Min. That's the old argument between a grounded chassis and double insulated chassis. Six of one, half dozen of the other really. If the chassis went live on this it would blow the fuse so it doesn't really matter one way or the other. The dangerous part is away from gefingerpoken so it doesn't matter. The only time you could get your fingers in there is if you open it up and that doesn't matter what you do really, there's always going to be dangerous voltages somewhere on the insides.
Yes, 311, it's all about saving space and I had greater need of saving space than any old Marshall. You could fit three of these things inside a Marshall headshell.

You use salt on the streets for snow ..... snow? What's snow?

The trannies had been sitting on my shelf for quite a while which is why they started to rust. I didn't get rid of it because I thought it looked cool. It's only the bell cover so it aint gonna hurt anything. They are unused before this.
The power transformer should outlast everybody because with one less valve the thing is loafing. I can play it all day and it doesn't even begin to heat up.
