Dude this is so incredibly f'kin rad. This is an intensely complicated circuit and you absolutely nailed it. Your patience and methodical approach paid off and I applaud you for showing that kind of stamina. Even if the amp sounded like garbage this would be a massive win, but it sounds phenomenal from this side of the digital fence. Just dealing with the Mouser interface alone for sourcing all these caps and resistors is a huge time investment, let alone comparing schematics and photos for proper layout. For this to be your third amp build is unbelievably righteous. Bravo man!

@MichaelWWestbrook Жыл бұрын

Thanks for the kind words. Your so right about mouser 😂 Getting the right parts from them alone is a win

I remember reading about the time/process Dumble created... I found out that even the length of a jumper wire could effect the build when my AC30TBX 63' reissue needed some love ..

@MichaelWWestbrook Ай бұрын

Yes, there are a lot of variables for sure!

@Ampman007 Ай бұрын

I’ve been building amps for years. Great hobby. It should be mentioned that Alexander Dumble knew his amps were unique so he coated most of the inside with a black silicone so amp builders couldn’t reverse engineer them. I could only imagine the guys that picked all that out of one of his amps just so I could be cloned. Great channel!

Very nice build. Have you ever thought of building a trainwreck? I've built a couple express'. They can do anything. Incredible cleans , all the way to super saturated, gorgeous, harmonically rich overtones. I've always been into tweed and plexi amps, but they do not even compare to a trainwreck.. the honeymoon phase will never end, lol. They are a very simple build as well

Congratulations for your hard work. I am a happy owner of a Dumble clone like yours with 15W output and you are right, this amp is just magic ! I wish modern amps could be built that way. Sure you now understand how hard it is to build this amp (and probably other types of amps are easier to build, who knows). Play a lot and if you can improve your amp please do it and show us all how beautiful your mind can be creative 🙏 A big thank you for your hard work ❤️

Hello Michael, great video, thank you. I too (started to) build a Dumble myself years ago. What an experience, as the electric idiot I was by that time, just with a pro looking over my shoulder from time to time and keeping me from lethal mistakes. I had a lot of flaws in it and it landed as a project in the basement, quite an expensive collection of spareparts. Your video encouraged me to restart and finish the project soon. Thank you for the impulse. May the electric shock be with you.

You did well to build that amp and not have any teething issues, congrats! I built a Ceriatone Kit of Robben Fords Amp, and it came out great ...no issues at all! I spent almost a month studying the schematic, the circuit layout & some high resolution photos on Ceriatones Build albums. I copied the lead dress from the photos, and the Amp has a very low noise floor ...super quiet! One thing that I did when I was working on the Front panel controls was to install the pots & switches thru the front panel & inverted, so I didn't have to work in the tight chassis. Once I was completed with that, I just removed the assembly and installed it correctly. Very happy with the amp! Enjoy yours!

Nice job for your third build! Especially with a Dumble clone. You took your time instead of rushing to see if it’ll work. That makes a HUGE difference. The only problem with building an amp that works right away is you miss an opportunity to learn why it’s not working. So if you or anyone watching builds an amp and it doesn’t work, just know you’ve been presented a great opportunity to learn about amps instead of just following directions. 🙂
