I would definitely be in for something in the way of the "Nano-Amp!" Mr. Bean, please let us know?!

Hate for my first post here to be a "wake the dead thread" but would love to see a madbean project like this!

I have two designs etched and partially populated. One just a couple of days ago. One is a variation on the Nano head and the other is more or less "Fender-y". So, yeah...this is still very much on the table. And, welcome to the forum!

Oh yeah!!

And thanks for the welcome!  Its been awhile since I've used pedals but decided to try some DIY to go with a valve jr I fixed and then modded to be more vox sounding.

Your layouts and PDFs are top notch, and I just got 3 boards from you last week, (cupcake, cave dweller, slow loris) really nice job, esp the plated thru holes and silk screen.

Hope to post once I get them into enclosures.

Please keep up the amazing work!

I'm sooo totally interested in this one.  I actually have a couple of firefly boards waiting to be built as well.  I would love to have a sub mini tube amp, but the MurderOne and Nano-head, are a bit pricey.. when this comes out I'll probably buy a few.

Bean, are you building in an smps to boost the voltage?

madbean

No, just cascaded diodes via a charge pump, like a lot of the frequency central designs. Gets up to around 80v or so. The heaters use a resistor.

I've got one of the original Murder Ones (one of the perf ones). It's a stunning display of Rick's skill and an impressive bit of miniaturisation. It's more of a curiosity or a cool object though than anything else. Mainly as my main amp is very low wattage anyhow. Actually I use it more as a headphone amp, which it's brilliant at.

Tube headphone amp? Yes, please!

A built-in cab sim would be way cool. I've never built a cab sim. Can anyone say if they work well?

I just have to keep bumping this one.  Whats up Brian?  Is this getting close, or are you just afraid someone is just going to kill themselves trying to assemble one  ;)
