This is great! For the traces, why not use 45 degree? and which chassis do you recommend?

Thought you all might get a kick outta this. I used a Hammond 1456 and fit my V2 boards inside to mimic the real a box later . JHS also posted this screen shot of their breadboard of their "box it later" which I was able to read the resistor codes and bread board wiring. I'm fairly confident I have ...

I merely scratch the surface compared to Martin's contributions. Looking forward to your progress!

Assuming you're following my layout since your boards match, you can do B25k or B20K. I use the 2W wire wound in my build for additional degree of accuracy and a little beefier than a standard carbon. It was my way to take a fixed bias and make it variable without changing too much and will fall bac...

Dang.. He's buying them all up. I guess it's sorta good that we know the 1 or 2 buyers for all things Dumble now? Who is J-Bo's amp tech again? Is he/she here? lol

very cool!

I added a raw and uncut sound sample to my photo album above of the Space Box. It's definitely interesting... unlike other reverb units I have (Victoria Reverberato, Strymon Flint, etc) I also noticed when toggling back and forth between my Reverberato that the Space Box does something really funky ...

"Bill Sundt of So[l]dano told me the Space Box uses a 12AX7 while the Surf uses an EL84, I think. He told me the Surf reverb sounds much better than the Space Box reverb." https://www.thegearpage.net/board/index.php?threads/soldano-surf-box.525080/post-5790958 Nice!! I'd love to figure out the Surf...

I ended up being able to borrow a Space Box to reverse engineer. Here is a photo album with the pics so far. 2x 7025 tubes which is interesting.

LOL I hate it when that happens!!

Congrats!! You unofficially have won Amp Garage Member of The Day with this build! Enjoy!

Thanks, Ryan! Let's hope it sounds as good as it looks :lol: Curiosity got the better of me, so I powered the unit up yesterday without any tubes plugged in. No blown fuses so far! Yay! lol I'm 99% sure with your attention to detail, you got this! The only uncertainty would be the OT primaries "cor...

Sooooo clean!! What an example build!

Thanks, guys. I showed Josh that there was literally one mention about the BBC-1 here back in 2008 lol. Never once did I see a pic of it. Not saying I'm an expert in all things Dumble, but I don't think it's talked about much. I remain strong supporting our open dialogue and community dissection of...
