    I have posted this before about two years ago, but I am going to ask again, because I am getting on a bit and can't remember the answers.....

    I am thinking about an AC15 build and wondered what is the best schematic/layout to use to get me as near as damn it to an original. I am sure the Ceriatone "Creme Brûlée" was mentioned......

    Many thanks in advance!

    The Ceriatone Creme Brulee is very close to a Matchless Nighthawk. It's in the ballpark of the EF86 version of the AC15. The Ceriatone Lightning is very close to a Matchless Lightning. It's in the ballpark of a top-boost AC15.

    Let's clarify. You want vol tremolo and cut? Isn't there a layout at el34world?
    I can share my topboost layout with you and the transformers used etc. it builds well into a marshall 18watt chassis. Two channels One: vol tone Two: vol topboost trem bass and presence (cut backwards :))

    It's a really really nice amp and quiet as a mouse

    Hi Andy, good to see you are still about on this forum. It's been such a long time since I was here last. The design you describe sounds exactly right to me and I would be very grateful if you could share the layout, many thanks.

    Best regards

    Dave

    Hello,


    Actually the book you're going to want to get is called "A service engineer's guide to the Vox AC30 Valve Amplifier" by Stephen Grosvenor. This man documented all of the old Vox amps and has put both the schematics and layouts of the Vox AC-4, Ac-10, Ac-15, and Ac-30 also. It's 57 pages and a good read if you want a vox that will be period correct in terms of it's spaghetti junctions and such. The best part is is that it isn't very expensive either. :)

    Oh, yeah, something I also forgot to mention.


    Depending on what you are looking for book 2 and 3 of "Building Vacuum Tube Guitar and Bass Amplifiers" by Tino Zottola has both the Vox ac-15 and the Vox ac 30 minus the trem circuits.

    Of course it is. But I was fortunate in the fact that I bought my copy a few years back when they were much cheaper. ;-)
