Hi just purchased from a market the above Pre & Power Amp very cheap

I remember these were quality Amps, I had one of their Signal Generators
years ago, made in the same case as the P51

Question is I have Kef 105 series3 Speakers these are rated at 4 ohms
and current greedy , so I am reluctant to try them,

Anybody driven these Amps hard into 4 ohms and did they cope OK

Also I know they are rare and sort after ,what do you think would be a
sensible reserve on Ebay, should I sell them

Have a look at 120035205868 on ebay - I sold a set recently for 250UKP.
I gather the class A versions are more sought after.

I thought they were fine with some pretty hard to drive Dynaudio 42s,
but not up to the reference that is valve :-)

If you want manuals I can email electronic copies to you - there's quite
a bit about the technical do-das.

Hi Thanks for your reply, those were yours were they , thought they go
for more than that, this one went for 700 AU dollars power amp alone
http://www.decibelhifi.com.au/category6_3.htm

I have the silver C21 Pre Amp so might make a slight difference

In 1977 Myself and a friend started Enigma Audio in Hove, with the
Enigma Variations range ,and Sugden ,Quad ,Lecson, and Naim were some
of the competition, I seem to remember our 100 watt Power Amp, in mine,
and others peoples opinion, knocked the socks of it for bass response
and shear grunt, mind you we had a huge power supply, DC coupled output
,and mj10005x and the other polarity output devices,

Our amp could double power into 4 ohms , this has not got the output
stage to handle that sort of power , the Supply Fuses are only 2 amp ,
Are your Dynaudio 8 ohm or 4

Manuals would be great please ,that is a working addy ,

Do you need power and the LT from power amp connected for the preamp to
function , seems odd ?

Many thanks once more, just noticed clock , time for a beer :-)

I seem to be having some problems with fetching the above list of files.

The fetches seem to terminate prematurely, typically after just over 350 kb
for a file have been downloaded. Tried connecting at various times, and
using two different browsers, with the same problem.

I have managed to get the first three files OK, but as yet have been unable
to get a complete copy of the final two.

Also, the final file is reported by software as being a 1660kb total.

Slainte,

Jim

Curious - I've just tried again (and put up a pic - 350KB if you click
on it) and it seems OK.

I have managed to get the first three files OK, but as yet have been unable
to get a complete copy of the final two.


I'll email them to you if you like - I know you haven't go broadband, so
be prepared for clogged up internet for a few minutes if you'd like them
sent.

Also, the final file is reported by software as being a 1660kb total.


My mistake - I did manage to get it down to 1MB at one point but the
quality wasn't too good. I saved the files as pdf from the scanner and
compressing pdfs is tricky, lesson learned etc.

I'll try again this morning as it may have been a temporary snag. I'll then
report back to say how I got on. I managed to get the first three files -
although the third one took me a few tries before I managed to fetch the
complete file before the connection ended.

[Just tried again at 10:10 GMT before sending this posting. As before, the
connection ended before the complete file had been sent. I tried fetching
the JPEG photo, and this was fine. I am wondering if there is something
odd about the server as I've noticed something else. The PDFs are not
filetyped correctly once the transfer ends. This is the case for those
which have transferred completely as well as the partial attempts. Yet
PDFs from elsewhere are filetyped OK. The JPEG also filetyped OK.
Perhaps the server isn't declaring the details exactly correctly?

Anyway, yes, I'd appreciate it Rob if you could email me the last
two files. Sorry for the bother.]

Slainte,

Jim

Jim, I just tried from here and they all came through with no
problems. I know this doesn't help you much, but it isn't the server.

That's strange. The server is (I'd assume) Google - it's one of their
free hosting things called Page Creator.

Filetype is a utility on your OS? I can only guess that the file gets
'mashed' in transfer, unless there's something up with the native PDF
tool in Mac OS X. At my end it says 'created by Canon' (the scanner);
'encoded by Mac OS X 10.4.8 Quartz PDFContent'. The fact verification
failed on the completed files does make me wonder. So much for universal
file types ;-)

Anyway, yes, I'd appreciate it Rob if you could email me the last

I've just emailed them - let me know if there's any problem.

Under RO the filetype is a file attribute which is set quite independently
of the name. 'Extensions' like '.pdf' or '/pdf' as used on other OSs can be
optional. However when transferring files via the net, a MIME map allows
the filetypes to be set automatically,

Hence when I download a PDF from web servers which declare the file type to
be 'pdf' the result would be typed 'pdf' on my machine regardless of any
extension to the name. The server will tell my machine/browser the file
details before the actual transfer

But with the PDF files from your server this does not seem to work as
normal. Works OK for the jpeg, though. This is what makes me wonder if the
http info being sent isn't quite standard. May be a deviation which
software on other OSs are happy with.

PDFContent'. The fact verification failed on the completed files does
make me wonder. So much for universal file types ;-)

I don't think there is anything wrong with the files as such. The machines
simply seem to decide after about 370kb that the transfer is complete,
regardless of the files actually being longer. No idea why this is
happening. I can't recall it doing so before, but I will now investigate
elsewhere. Not a browser problem as I tried two completely different
browsers. May be a connection software problem which I've not fallen over
before.

Anyway, yes, I'd appreciate it Rob if you could email me the last two
files. Sorry for the bother.]

I've just emailed them - let me know if there's any problem.

Many thanks. I have responded by email. :-)

Rob I am new here.

Also just picked up C51 and P51 pair.
Have ordered new electrolytics to fit.

Can't access the link you posted here, says I need permition. Have requested permission with my boilerpeopleltd email address. Can you take it out of your spam if it has got stuck there?

My main question is how to connect speaker cable for bridging? I suspect after puting mono switch across connect to two reds, right? OR is it red one channel black other channel?

Other question, is there a bias adjustment at the pots to fine tune?

Many thanks in advance.

I am fully conversant with designing and building valve amplifiers. know nothing about BJT designs.

Rob any possibility email me direct also?

boilerpeopleltd (insert here the ampersand sign) gmail (insert here .com)

Just avoiding spam bots.
