    This project originally started in a discussion in 'Ampage Area' started by hcsterg, Jul 22, 2017, called "AMPS?"

    Since then, most of the pictures posted in this discussion have dissappeared :oops: because of a collapsed picture hosting provider :confused:... Add to this that I'm very slow by lack of time, but now I think that I'd be able to finish that amp project at the end of this summer :eek::).

    For those who remember, I presented the construction of 3 combo amp cabs from scratch (2 small, 1 big) with some details. But without the pictures posted in anymore, I think it's unfortunately useless to continue it, so I start a new discussion with one of the project : the Serial Tone Killer (STK).

    Quick cab story :




    So the one which is concerned this time is the biggest one - the others will come... Later... :rolleyes:



    I designed the front and back panels and have them laser-engraved :



    Now you are guessing what kind of project it is ;)...

    Instead of reverse-engineering and designing all the circuit and layout, I opted for a Ceriatone OTS 100 set of boards to serve as the basis for my project. Let me recommend Ceriatone stuff - it's premium quality, thoroughly built - a reason why I choose them :


    As you can see, I ordered the set of faceplates to have the correct dimensions and positions in order to design and draw mines. I found this much more fast and practical to use them as a model than trying to guess...

    The rest of the parts for the amp chassis (transformers, hardware, other components) is on order and should be delivered next week, the time - I hope so :rolleyes: - to finish the current amps service and repairs...

    So Wait and See... :D

    Very cool. I forget, do you sell them, and ever ship to North America? I suppose 240 to 120 volt conversion may be a challenge.

    Thank you, Guys !

    Thanks !

    I hope that you are patient... ;)

    No, sorry : I'm not scheduled for any selling production. It's only a part-time activity, when I only have time to do it, and this point is rather unpredictable ! Add to this the problems of UE and US regulations compliance, etc... And you get the picture. I don't want and have no time nor money to follow that path - at least for the moment.

    Continuation :

    Chassis front and back faces drilling and presentation :


    Chassis ans cab presentation :



    Next step :
    - chassis to cab fixations
    - circuit and components implantation

    The job is on :)... Wait and See ;) !

    Those cabs look beautiful!!! Real class.

    Looking forward to seeing the end product!

    You never let us down. Your work is always a joy.

    Those 9v outputs are a genius idea. Do you use rectified 6.3v from the main power txf, or is there another small power supply?

    Thanks Markeebee - creator of the "Bent" brand :D !

    The transformer that I use here is a toroidal one (more powerful and lighter than a EI one) which has 2 additional 15VAC separate windings : one is used for the footswitching relays, and the other is used for the digital reverb and for the external effects - that I may put on the amp occasionally, inserted or not in the footswitchable FX loop.

    I am also considering to heat the preamp tubes in regulated DC 12.5V also with the relay supply (which only needs 5VDC with a ridiculous current)...

    Thank you Guys :) !

    I am now studying / drilling / populating the chassis inside / outside. This needs some "cunning" to get there... I expect to post the pictures this evening (fr) if everything continues to go well...
