    Amps From Scratch... Well, not completely - but nearly, OK ? ;)

    This is my "incredibly slow, not for sale, personal, part-time, amateur" guitar amp design and construction. And I'm surely not alone here doing this, right ? :) Maybe some members may have seen my amps on another forum too...:oops:

    The Val-King :

    [​IMG]

    8 Watts
    8" Vintage47 Hemp cone AlNiCo speaker
    integrated EHX HGN digital reverb
    gig bag

    Quite compact :

    The Orient-Express :

    Just a tad bigger than the Val-King :

    [​IMG]
    [​IMG]

    4 Watts
    8" 50s Utah reconed AlNiCo speaker
    integrated EHX HGN digital reverb
    tremolo (footswitchable)
    feedback and triode/pentode switches

    That's not a guitar amp, it's a work of art! I mean, MAYBE it's a guitar amp.

    Thank you Guys ! :)

    I design my panels and logo in vectorial drawing via a freeware called InkScape, able to generate .eps and .dxf files compatible with the laser engraving machines of a local specialized workshop. Well, it's quite costy, but the result is neat and durable.

    Another one...

    Maybe one of the smallest standalone guitar tube amp ever built ? o_O

    The Radio-Tone :

    [​IMG]
    [​IMG]

    2 Watts
    5" OakTron AlNiCo 60's NOS automotive speaker
    1 tube ECL86/6GW8
    230VAC directly powered (no adaptor = standalone)

    The sound - quick sample with a Squier Std Strat and a EHX Cathedral Reverb, natural overdrive of the amp :

    Lovely work.

    Do tell us more about the power supply, I see you have a tubetown toroidal in there.

    And how do you get the 2-tone tolex, is it painted? Looks beautiful.

    Lovely amps...
    I am really enjoying my 5E3 build almost every day.

    Would love to hear more about the way you do your face plates. I am playing with a 3D printer to see if I can maybe make some special faceplates.

    Fantastic! Extraordinary aesthetics, cleaver use of reverb pedals and, cleaver design and of course, the sound from your audio file is excellent!

    Thank you Guys !

    Well, there's nothing mysterious about the toroïdal transformers : usually more compact, as powerful, with the adequate windings, bridge rectifier, choke, caps... Classic circuits, in fact. In the Val-King, I used the tt-t-56 and in the Orient-Express, I used the tt-t-47.

    In the Radio-Tone, I used a 6g15 Reverb power transformer from Hammond (290WEX) for maximum compactness. No choke here : no room for it !

    About the Tolexing, I used 2 (or more) colors of Tolex, cut it to size, and made seams. It's similar to wallpaper putting, but the secret is in the glue : I use tubetown SG-5 applied with a brush. No paint, except for the black satin inside the cab.

    Some quick tips - here on a larger cab :

    Well, I don't know if faceplates are interesting to make with a 3D printer...o_O

    I design my faceplates using a vectorial frewware called InkScape, which is able to generate .eps and .dxf files compatibles with laser cutting/engraving machine of a local specialized workshop. It's costy, but the result is neat, exact and durable ;

    This one below was inspired by the Valco / Supro Spectator amps look :

    The Comet :

    [​IMG]

    5 watts
    10" Utah 50's AlNiCo reconed speaker
    Diodes / Rectifier valve SW
    Feedback SW
    EHX HGN reverb

    ... With matching guitar ;) :

    My goodness! You sir are a incredible talent. I love the designs and execution. When I retire I plan to produce tube amps and guitars for sale. I hope that I can achieve the quality and creative levels that you're able to. Kudos to you!

    @tubelectron, if you can still "Edit" your post, delete the "Red X" image and "Upload a File" again.
    I had that happen once, never understood why, but removing the original image and uploading again seemed to fix the issue.

    As for posting my projects - I've started the 5F1 champ thread, but I'm really just an infant in all amp stuff.
    I'm hear to learn and borrow ideas.

    I think you might be a wizard. Those are all gorgeous and a lot to functionally cram into such tight cabinets. Out of curiosity, why did you decide to just stick the whole pedal in the amp instead of gutting it and using the components without the enclosure?

    Also, if you ever make an extra comet you don't want, I'll gladly help you free up that space.
