  • I call it the "Hound Dog Deluxe"

    Hi !

    I tweaked an amp closed to the Fender and Alessandro design with an effects loop.

    You can find some views here and there.

    Clic here for some samples :
    Sample 1
    Sample 2
    Sample 3
    The "Blue Bossa" Theme

    You can find some interesting design on this amp.
    I introduce a circuit to empty the capacitors of dangerous hight voltage after turn off the amp, about thirty seconds content to have almost no residual voltage.

    You can also find an interesting filtering design by L/C, on the High Voltage source with a "non-center tap" transformer and silicium rectifier bridge. This helps the amp to be more quiet and give a better stability of the voltage value at high volume and so give a better dynamic.

    The effects loop is totaly parallel, very inspired by the reverb design of the BF Fender amps. It have the less influence as possible on the signal way and so is the more transparent than possible. It work very well with a TC G-Major-that's what you can hear on the samples.

    The amp is totaly class A with two 6V6 tubes and have a power of 10W very useful.

    I use to play it in clubs and rehearsal with my differents groups and never feel it weak !

    You can find all about it here.

    It's in french but if you have any questions I'll try to answer the better I can.

    To help you :
    Calculs want to mean Maths
    Lampes want to mean Vacuum Tubes
    Schéma is for schematic
    Déphaseur is for Phase Inverter.

    You can find more samples below the page of my article. (DEMO)
    Plenty informations are available.
    Schematics, mesurements, Maths, components ...

    Nice build, thanks for sharing the details. I don't have audio on this PC, will come in and listen to it later. Class A 6V6's usually sound sweet as can be, my favorite small amp sound, personally I choose them over EL84's any time though the British tone is also very popular.

    Congrats!

      Thanx a lot !

      Yeah 6V6 are really sweet !
      Anyway with EL84 we can make very nice tone but usual mistake is to think the preamp as we are working with EL34 power stage. EL84 has got is personnal voicing and reaction that we have to concider seriously before designing the preamp and the PI stage too.

        If you've got lower +B (near 200 VDC) and availability for 3x more heater current draw(a whopping 1.4 A), one of the sweetest tubes I've ever tried are the 6Y6. The sweetest small amp tone, but the poor thing pulls KT66 level heater current!

          Yeah, that's pretty true (imho) but de concumption ratio is very bad !

            Correction: 1.2A for 6Y6 heaters.

              I live in the UK and am always hearing Americans ect say that British amps are better, whats your opinion. I have just orded a Fender Hot Rod Deluxe as I think fender do the best clean tone. fender cost more in the Uk because its american and mexican made, shipping costs ect, with marshall, Vox, Orange it works the other way round as they are made here. I think if your into metal and hard rock marshall are great, but for clean fender all the way.

                It's all about taste and the tone you're trying to achieve, IMO. The British sound is very characteristic. If you hear some of the folks who set the Vox AC30 up on youtube exactly like Brian May, you hear it and instantly identify it as Brian May tone. It's a signature tone.

                I can't say for American taste, I only lived there for a while. IMO I think the opinion varies wildly in America. For instance, in some places I've seen the Fender Blues Jr. is often mocked as the "blues amp with british tubes" as if the two weren't compatible. A friend of mine, local blues musician, uses a blues jr exclusively and is happy with it and he has no idea what tubes are in it. There have been several American classics like the Trainwrecks made with British tubes and they sound amazing.

                I don't think we're gonna find a definitive word on the subject. One of my favorite combinations is still Clapton playing the blues through a Fender Bassman, but I wouldn't complain to see SRV playing through a Marshall Major

                  Actually you can have both tones (british and american) out of a 5F6-A Fender Bassman or a Marshall JTM45 - they're both the same circuit (probably out of a Vox AC30 too). The tubes might be different as well as the trannies, but the major difference in tone is caused by the speakers IMHO.
                  Hook a Bassman to a 4x12 Marshall cab and you'll see what I mean - british rock tone. Or, use a JTM45 with a nice Jensen C12N and you'll get sweet tweed clean Fender tone - or if you dig into it - a grunting Bassman sound.
                  The Hot Rod Deluxe is not what I call the vintage clean Fender sound, though it's alright.
                  As jmaf said: it's all about taste.

                    I agree about speaker, it's a big part of the tone personnality. My 6V6 Fender inspired amps sound pretty british with Celestion speakers.
