It's not. Not even close.

This is the amp that got away from me. It was local to me. The former owner put it up for sale on Facebook marketplace a couple days after I left town for Thanksgiving vacation. He listed it for $600. I spoke with him about the amp and how he acquired it (he's originally from New Jersey). I offered ...

I'm curious why Drew would be selling them. As the new caretaker of the Dumble name I'd assume he'd be hanging on to as many amps as he could. I know he's a dealer so he could be selling them for other people.

I figured I should start a thread for my new build. It's probably going to take me forever to finish, but at least it'll be documented somewhere.

This is going to be a #124 with 2x6V6s.

Here a thread from a few years ago that has a schematic towards the bottom. This was the poster's best guess from an online pic. https://ampgarage.com/forum/viewtopic.php?t=34565 Here's a pretty good pic I found from a search. bloomfield.jpg Also, here's a video from a fellow Amp Garage member. http...

Looks like he's endorsing them. I lose confidence rapidly when someone misspells the name of their "amp designer" (Jim Kelly instead of Jim Kelley)...sigh. Pricy stuff ! I may have spoke too soon. He moved to Arkansas in February to work for them and now he's already moving back to Austin/Santa Fe....

Smart Belle is out of business. They did attempt a solid state "Dumble". It was about as successful as his solid state "Trainwreck". I'll say this: Lance doesn't give up, although it does look like he may (finally) be out of the amp business. Funny you should mention it. I'm pretty sure he's affili...

If you have an extra of either transformer let me know! Thanks!

These are tube amps. Smart Belle makes/made a solid state Dumble for a while.

Hey, folks. I'm going to be starting a new Dumble build within the next month or so. I'm going to do a 2x6V6 build. I was looking for input from people that have done similar builds. Any certain preamp versions you prefer with 6V6? Any other things you ran into during the build? Any layouts/schemati...

Ha! I remember he kept getting banned from a FB page I frequented. He had several accounts.

Sorry to hear that.

That stinks. Hopefully you get it soon.

Congrats! Any plans to reverse engineer it?

Has anyone been able to dig into the 19 a little more?
