    Dynaco Mark III guitar amp

    Post by bluesboy on Sun Jun 06, 2010 2:51 am

    I own a Dynaco Mark III guitar amp. Although i can find loads of info on the Mark III hi-fi amp, I haven't had any luck locating information on the guitar amp. Hoping this forum can help.

    thanx

    Bluesboy,

    Are you sure that your amp is not just a stock Mark III with a guitar input jack and maybe a different speaker output terminal? It is possible that you have a basically stock Mark III that someone adapted for guitar use. Why don't you post a photo of your amp up here on the forum? Maybe by looking at a photo of the amp one of us can determine what you have ...

    Hi Bob, thank you very much for your prompt response. You are probably right about someone having likely modified a stock Mark III hi-fi amp. I'll have to borrow a digital camera and then send the image.
    cheers

    Hi,

    If you do post a photo you have to host the photo on another web site. This forum is supposed to host a photo but it just doesn't work. Join Photobucket or some other photo hosting web site and then just use the "Image" button at the top of the "Post Reply" box. If you can't post the photo then just Email them to me at > Bob01605@aol.com as an attached file and I will post them for you in this thread.

    FINALLY a definitive answer:

    This was posted on another website by Conrad Sundholm on September 19, 1999. Sundholm is the founder of Sunn, a manufacturer of guitar amplifiers since acquired by Fender.
