The Sushi Box FX Secret Society

I know this is a wild guess, but I think it'll contain resistors, capacitors, and a tube.
You are 100% correct. It has some other things as well, but that's the bulk of it.

Oh boy... what’s the est. price tag so I can ready my body and mind for when I see it? Point to point construction and tubes is something I gotta see :bookworm:
Estimated pricetag is $300. It felt fair for an X style preamp with more expensive components that takes more time to put together.

I'm gonna say it's a HiWatt. Is it a HiWatt? It's a HiWatt. I'm sure of it :)
A solid guess, but not a HiWatt.
 
So this is the circuit board. As I said a little different than my usual stuff, and took a bit longer to put together. Silkscreen has been redacted for hype purposes.

mmm 400V poly caps....SOLD!

Since you havent done one yet, could be an old Fender, Traynor, Sound City or....West Fillmore?

Sorry for the pot shots...
 
Have you been hanging out with Josh Broughton?
Unfortunately no, we're pretty far apart geographically. Seems like a neat dude though.

It looks like a very " Noble " adventure to me - especially at that price w/ only one tube to boot . Bet there'll be some tube rolling going on with that one whether my guess is right or wrong .... Kelly
I'm still working on my all original tube preamp/D.I. to do what the Noble does, that one is still a ways out. Not to mention if I made a big tube preamp/DI that sounded amazing, only doing a limited run would be a pretty bad move on my part. When that one is ready it's going to be a standard build that will be available for preorder.

OooOoOo a reasonably priced tube DI would smash the competition! But I would settle for clean bassman-style preamp
Reasonably priced tube DI will come eventually, but definitely will not be limited run, that will be a full scale thing that everyone will get a chance to pick up.

I haven't done a direct bassman preamp, but looking at the schematic (5F6-A) you're not far off, but every version of the Bassman I'm familiar with has a couple tubes in the preamp.
 
I have no idea how to read circuits but after staring at the numbers on the caps/resistors on Nathan’s board and looking at Marshall/Fender/Ampeg circuits... could be Marshall or Ampeg? Maybe Ampeg. I have no idea what I’m talking about. It could be a boost/tube DI for all I know.

EDIT: I posted this at the same time as he denied it was a tube DI. The preamp/boost mystery continues!
 
D.I. is one of those things that sits in the back of my mind and nags at me, I know it's something people want, and I have a few hundred dollars' worth of transformers sitting on a shelf in the workshop taunting me. I actually meant to get at least an initial D.I. prototype in the last batch of boards I ordered, but with everything going on I completely forgot to design it.

That DI shootout is going to be something to hear about. I imagine at this point it’s something like Carnhill vs Cinemag vs Jensen vs Lightning Boy etc etc etc...

WOW! no SMT components. That is indeed a departure.
They're actually all hiding on the bottom of the board :whistle:

The power supply is still SMT (high voltage has to come from somewhere), and is on the bottom of the board out of sight, anything that touches or even comes near the audio signal is carbon comp resistors and film caps though. The typical SMT caps I use on X series builds are 250V caps so I usually run them around 235V, but with 400V film caps I can run it at higher voltages, right now I have this one set at 300V.

No surface mount, you have my attention -

Please tell me this will convert you to turret

EDIT: Spoke to soon.. arggg, well let me put away my white gloves..

Sorry :P SMPS is the best way to get high voltage into a pedal in my opinion, and the smaller the parts I use on the SMPS the smaller the box I can fit it in. No surface mount anywhere in the audio portion of the circuit though.

Well I guess as long as the noise stays in the PS. How much to make everything like this going forward? like a NOS component upgrade lol, I'd take the hit lol
