So a new SVT pedal is getting closer to the day of light, you woun't be able to help yourself now.

Ah I'm not even that big an SVT fan, but I want one of those purely because it looks bloody brilliant
I guess that shows how bad my memory has gotten, I think I asked you if you were going to sell those SVT inductors by themself over a week ago.
Just three tubes?
I won't have the big order for another couple weeks, but yes, that is the plan.
If you've ever thought about doing a clear plexi bottom on a pedal, I vote this one
I'm very curious how you are going to mill the slots over the tubes, those tubes are very close so 3 separate lots of slots might not work real well.
Best to hand it over to the engineering department, kids are good at working these things out.

I thought the Firebox was a tube power amp with an inbuilt load, I thought Nathan was planning on using the Hammond 125A transformer for the build.
With a resistive dummy load on the output you should be able to drive headphones or even a speaker if you switch out the dummy load.
My impression was that a pre amp and a power amp was all going into one 1590XX or 1590DD box for the Firebox build.
I am going to try to make a small power amp by itself within a 1590BB box, that way I can use any of the C2CE pre amps to drive it into a speaker or headphones. My version if it works will only be a few watts at most, basically the power section of Rob Robinettes Bassman 5F6A-M Micro PP amp.
EDIT: There is a company in the US that makes tube amp transformers that has a better frequency range then the Hammond 125A but a similar size, I can't remember their name but if it comes back to me I will post it. (I'm sure someone here will know)
EDIT Again : I just found the article on the Firebox I remembered reading :
Firebox - tube power amp emulator
Now that I have my own section I'M GOING TO POST EVERY SINGLE IDEA I HAVE HERE. I have a dedicated section on Talkbass where I can show off things like finished products, but people there don't enjoy geeking out about PCB designs like we do here. So this is a bit of a misnomer, as it's not...

Solid question, I'll measure it when I get home. Suffice to say it will be a lot, I expect it to be around the 1000mA range, allowing some margin for warmup.
I used 125A for the initial prototype over 2 years ago, and the frequency response is garbage. I already found one I like better and have used it in my bass headphone amp, but I haven't gotten around to actually revising the Firebox design.
Defo portable! It'll squeeze onto any pedal board
You sure that's the one you would choose...?If you've ever thought about doing a clear plexi bottom on a pedal, I vote this one
Man if you drop the Furthermore, SVBT II, and the Grand Slampegg all at the same time, my brain will be happy but my wallet will be very upset with you
I stand corrected, or maybe both exist!I thought the Firebox was a tube power amp with an inbuilt load, I thought Nathan was planning on using the Hammond 125A transformer for the build.

I'll take a look at the forum coz it's be interesting, but Nathan's first words are spot one, I don't geek out so much around the build process
mainly coz I know if I ever attempted to build a pedal it would be absolute garbage! I have very little talent for that kinda thing.I'd be majorly interest to see how you progress with your project though, that fat girthiness that comes that only comes from pushing a power tubes into a transformer is the bedrock of good bass tone.
To have that in something you can easily carry about would be truly amazing.
I'm now gonna back search this thread again as it's a long time since i read Nathan's post about the Firebox.
I think it might have been a transformer from Musical Power Supplies that has a better response on the OT then the Hammond.

@Tassieviking I've mixed up two posts in my head in the last two years! And I'd've put my life on the fact that the prototype had a More as the preamp!!
I must be getting old
I must be getting old
I was looking at a single 6V6 (5-6W) tube power amp in a pedal-sized box, and even that wouldn't fit in a Noble-sized box. If a 50W tube power amp was possible in a small box guitarists would kill for it, but alas still a pipe dream. Anything over about 1W is just going to be too big and too hot
