    Thanks for a great site. This is the best site I have been on for instruction, code that compiles and works.
    Looking forward to your applications.
    Very best regards.

    I have owned both the Chartwell LS3/5A and the Spendor LS3/5A Spendors (and still do). I use a custom made tube preamp and power amp to drive them. I love the sound. I just acquired a pair of Spendor SP1's. They take the sound of the BBC developed speakers a step higher Mr. Spencer Hughes was by any measure a very brillant designer who knew well the sound of live music and how to design and build speakers capable of reproducing that elusive sound. It is a shame the speaker design lab of the BBC is no more.

    Mark, Thanks for putting up the great inside & out review of the lovable, if rather directional speakers. I have three pairs, two sets run as a set, due to their impedance value & the third run with a Cannon vertical speaker set (sound quality no were near as good), to get over the directional nature of the Rogers.
    One minor question, any idea how to clean the exposed cone without damaging it? Ok I've had them for 15 years (?) and I've tried to resist the temptation, but the girlfriend is itching too, and before they are dusted into oblivion any advice? ...... other than become celibate!
    Regards Bob

    I have been trying to learn about programming for the past 10 years. There aren't any books which will take you through step by step like this one. This has encouraged me to learn more.
    I have book marked your website and looking forward for any updates

    Thanks for the articles on design and building gainclone amps. Very helpful to understanding what makes it work.

    Thank you Mark for all the valuable information on the MF A1.

    I have owned mine since it was new in 1989, and I took the plunge and opened it up yesterday. The tansformer was completely unsecured, and one of the 10000uf caps was rolling around. The other three have bulges and look ready to explode.

    Amazingly, I have been using the amp regularly, and I was oblivious to the problems lurking within.

    I shall now start the restoration process, replacing the electrolytic caps and the pre-amp as per your recommendations.

    Thanks once again.

    Mark
