Two 'annoucements' about the audiomisc website. :-)

1) I've just rearranged the folder/directory structure of the site as this
will make adding some future items easier. This means that some of the sets
of pages have moved. If you revisit, please bear this in mind as some old
bookmarks may now be out of date. Sorry if this inconveniences anyone, but
I thought I'd better bite the bullet on that asap rather than leaving it
until there were more pages, and the versions on my old host site were
gone!

2) I will shortly be putting up a new set of pages on Jim Sugden's early
Class A power amp designs. These are the ones from the late 1960s and early
1970s. I'll say more when they appear. I'll be interested to see if anyone
remembers - or ever saw! - the Sugden Si 402. ;-

However...

I have things like manuals, circuit diagrams, etc, for items like the
Richard Allan version of the A21, and the early JES versions. But I don't
have any good *colour* photos of these amps in good condition. Nor much in
the way of magazine reviews, coloured publicity leaflets, etc, during the
1966-71 period for JES. (Although I do have some copies of the adverts from
the magazines of the time.) Hence the initial versions of the pages lack
colour. If anyone has suitable colour images and is willing to let me have
a copy I'd be grateful if you could contact me by email.

Please *don't* email any files to me without checking first, though, as I
don't have broadband!

Initially, there will only be a few JES pages, but I will add more as and
when I get a chance. I have included circuit diagrams for those who may
find them of interest. (I am also planning more pages on Radford in due
course.)

Slainte,

Jim
