Tiny Tweed Tube Amp

My DIY tiny tube amp project, with a 12AU7 (ECC82) tube/valve based preamp, an LM386N-3 based power amp, wrapped in aluminum and tweed. Schematics are shown in the video.

Ahh, some electronics works, coffee and glue fumes. Right back to the 70's. Very nice work! Sounds great for some studio/bedroom noodling.

Now let’s see you get a reverb tank in there:-)

This video is so nicely put together as well! Brilliant, it's people like you who make the future a brighter place for all of us. Keep it up! :)

Congratulations! Very good your project. Could you share the parts list and the circuit?

[bondjovi]

I bet that 12AU7 pre-amp would sound nice with some germaniums on the power side.

This is awesome man - I came here sampling sounds of the LM386, looking to build a mini amplifier to partner my 1x5 cab without having to wrap my head and wallet around hefty transformers for a full tube power amp... This seems like such a nice compromise at this sort of scale. Thank you for the inspiration.

Great project and video, thank you!
And you have the cleanest desk I've ever seen! 👍👍👍

My God! I could definitely buy this little thing.

[SergeiVlassov]

The tone is not exciting, but the amp looks great! Lovely design! And great video too!

[jimhough]

Nice little practice amp! Could use other ic for more power and higher voltage, which I'm sure would help out on tube plate. Plenty of TDA... chip amps out there that operate at like 36 volts or so. Good tone, but higher voltage might make that 12au7 "sing". Or maybe a 12ax7?.

Ahh dude, you should try it with a lm380, just toss a little low pass filter on the output or use an output trafo.

Hey i want to build my first tube amp and ur s look really nice!!! is their any
possibility to get a PCB or maybe the eagle Files ? Greetz

[mikelewis]

If you’re up for the challenge again, I’d buy one!

[stacygraham]

I don’t have any electronic skills, do you sell these mini amps

[BenPortmanlewes]

A thing of beauty, I design print and assemble multirotors, but I can't do that. Have a pint sir!

[peteytwofinger]

just curious why anyone would use an lm386 when they could use a tda7052a . i mean if you are going to do it right ...

[stephenfeeney]

If you decide to sell these in kit form, please let me know

Hi, I have spare 6z4 tube (I couldn’t buy only one, they sell them in pairs) can I build a single tube amp with that tube, it’s a rectifier. I just started to learn about tube circuits.

[jafethuerta]

Could you make one and ship to London ? Tell me how much 😉

As a guitar playing hearing aid repair man I gotta say SWEET !
