    Does anyone make one?

    Haven't seen one. Imagine the flack from Howard?

    well, you wouldn't sell it as a d*mble clone. I think there are enough clones out there that a kit wouldn't be an issue...

    Maybe it would be more of an issue since schematics and part lists would be out there (actually, they already are).
    Who knows? One of these days when I get some spare time, I'll perfect my Bassman conversion;)

    I think even a step by step set of instructions along with the many schematics that are out there would help advanced beginners like myself...

    What would you be willing to pay for such a set of instructions with the caveat that you cannot share them with anyone? (kinda like an prohibiting the copying and distribution of his book ;))

    Well, if it came with a complete parts list, layout, step-by-step instructions and if you could buy an off-the-shelf chassis from weber, allen or hoffman, it'd be worth $250-$300 I would think.

    Then, basically you could buy all the parts for an additional $300-$500, not including the head cab and depending on whether you went with MM or New Sensor/Mojo transformers.

    It'd be cool though if you optionally sold a bag-o-parts which would include all resistors, caps, pots, jacks, switches, etc. so the end-user has only to buy the transformers.

    Front plate is another issue...

    On a related note, I'd love a kit which mates a fender AB763 preamp with 4 EL84 output tubes running class A.

    I have a torres amp with that configuration but with 2 EL84s and it sounds fabulous. I'd love to have something similar but giggable...

    You'd need a board too. I'm getting a headache just imagining the customer service calls:eek:

    Right - you'd need a board too but you could just give instructions on how to fabricate one and along with the layout the user would make one. You'd have to sell it as-is with no service provided. Perhaps, optionally the customer could send it in and you could repair it but that would have to have a minimum charge to make it worth your while. Or, you could just sell it as if it were a bag of parts and the only warranty is for the parts themselves. Anyone needing debugging could use the various weber/hoffman forums with you occasionally making an appearance.

    And of course, it couldn't be a d*mble circuit but there are enough variations that you could do something close without being a real clone.

    It'd be cool to have the option of reverb, for example...

    And of course, on top of that you would optimize it for your special tubes. :)

    why on earth would you want to eliminate all of the even order harmonics from the power amp?


    or do you just mean warm cathode biased AB?

    Interesting concept for sure. It would probably take a month or so to work out all the details, have someone "test" the documentation by building an amp, publish the documenation, etc.

    I wonder what sort of demand there is for "product" like this.

    Maybe some time in the future when better paying work isn't available.

    Sounds like you'd be perfect!

    Let me know if you want some help with documentation, artwork/layout advanced beginning electronics input, etc. :)

    We could also do some cross-promotional stuff.

    This is assuming that you have actual accurate schematics to an ODS, which I think is the most questionable part.

    There's a guy online that sells schematics, and he swore he had them... but they were just the same old Rumble schematics.

    That's going to be the hardest part.
