    Marco, it seems that Sugden have had a few model changes in the last fifteen years or so. HiFi dave has bought in a current A21 and loves it to bits, although he claims the other models are a bit softer-toned.

    The A21 I knew well, as it was a loan amp for a few years, actually sounded a bit brightly lit and slightly messy. I happily admit not to looking inside, as various bits may have needed replacing and the thing properly set up.

    While we're on UK made amps of substance (and I don't mean recycled 1950's PA amps), the current Rega Elicit should be considered too..

    I've known about it for a long time; this advert was taken from the July 1966 edition of Hi-Fi News (before it became Hi-Fi News and Record Review).



    I hadn't realised the output transformers were made for Rogers by Radford. Looking at the interior shots provided by André, (http://theartofsound.net/forum/showt...483#post136483) it would appear that there are similarities with the Radford STA 25. These being the use of solid state rectification and capacitor-choke smoothing. The Rogers appears to have, at least, separate smoothing circuits for each channel, with perhaps individual channel power supplies going back to separate secondary windings on the mains transformer.

    Of course the main difference, and one which I believe gives the Radford designs the edge, is the use of an ECF82 triode-pentode in place of the usual ECC83 phase splitter (or in Rogers case, the ECC82).

    Regards

    I was only 16 in 1966 and £50 was for me a fortune! However if I had had that sort of money, I would have gone for a Radford; they were made in Bristol, my home town.

    Btw, any idea what Shure cartridge that is in the accompanying advert? I don't recognise it.
