Hello Paul,
Yes, I would be interested to see the pictures of the AVO CT378B
What was the Marconi sig gen model number? I missed it.
No need for pictures of the Marconi unit. I might know it from
the model number.

Okay, John. The Marconi's a TF 2002AS. I'll post you a pic of the AVO
2morrow as I'm a bit shagged-out right now (bank holiday boozing here
2day).

Yes, I know that unit, I have a 2001
Repairing that unit is not dead easy for hobbyists.

I am assuming that AVO at Dover were useless with your
enquiries regarding information on the AVO CT378B

If you wanted a good back up signal generator,
that is dead easy to repair. Here is one for sale.
Marconi TF 144H 50 ohms output Z. BNC connector.
10KHz to 72MHz
http://cgi.ebay.co.uk/ws/eBayISAPI.d...4746 090&rd=1

I like that model, for a number of reasons.
Very stable frequency wise (when warmed up).
It has that nice smell inside that you get from valve gear. LOL
Everything inside is getatable.
Big knobs and easy to read dials, good for failing eyesight.
When the attenuator gets smoked by accidentally pressing a
microphone push to talk button of a transceiver under repair
on the bench, it is very easy to replace the resistors in the
attenuator.
It was not that heavy that I couldn't hump it up the gangways
of ships, decades ago, to do radio service work but it is way too
heavy for me now. Heh heh heh...

You might like to check out how far away that unit for auction,
is away from you. I wouldn't pay any more than 45 quid.
Even 25 quid is right on the limit for me. But if no one bids
you could get lucky. I bought one here in Australia for $10
at a Ham fest.

I only mentioned the TF144H incase you were looking for a
good cheap sig gen to accompany your TF2002AS do some
serious radio receiver work. Both have good attenuators.
Having two good signal generators would help you out with
all that filter and interference work that has been plaguing you
over recent months. One sig gen as the desired signal, the
second sig-gen as the interfering signal etc.

I'm screwed without a circuit diagram, anyway. Some people never seem

I just assumed they'd blank me on the age of it - like Tektronix - and

Sounds like a great idea, actually. The problem is of course that even
here we're hardly spoiled for choice IRO older test equipment. Finding
one of those particular models for sale in this country would be
tricky, I'd imagine. Anyway, I'm about to mail you a pic of the AVO,
so keep an eye open in your inbox and don't delete me as spam!
Admire those classic 1950s lines.....

WHAT! YOU ARE KIDDING ME!
ARE YOU STILL ON THE ****?
It is a bleeding Marconi. I thought they were made in
Chelmsford. That is just up the street from where you
are in London, by Australian standards of distance.

The unit I have been going on about is for sale in Beds UK.
Where is that? Bedfordshire maybe. Four streets away
by Australian distances. Current bid 0 bids. 25 quid.
You didn't even look. Cripes.....tearing hair out.

Whoa! Calm down there, John. I'm simply not taking the risk of doing
anything Interenet-Explorer related until I've got the patch for the
sasser worm that's flying around the world at record speed. Sure I'll
follow your link as soon as it's safe to do so. Gimme a break will ya?
;-)
BTW, I've just posted you the photo of the Sig gen. Took a bit longer
than I meant to as I've been faffing about with photo software trying
to enhance the image. Taking flash photos of shiny, black objects is
pretty tricky, I've discovered...

The model number ain't gonna mean a lot to anyone as this is a very
old piece of kit (1950s) that I keep mainly out of a sense of

picture of the socket to a.b.s.e under this same thread title...
BTW, there's a 5p coin shown for scale, but since that won't mean much
to anyone outside Britain, the outer of the socket is approx. 1" in
diameter (which won't mean much to anyone in europe but it serves them
right for adopting the metric system.:-))
======================
Since Britain is part of Europe you probably mean 'anyone in continental
europe'

Just for your info ,the metric system was introduced /imposed by Napoleon
(eg more than 200 years ago)
For once he did the right thing .

The metric system also the law here in the UK. You can't sell stuff in
pounds and ounces or feet and inches. Miles are the last bastion of
the imperial system (on road signs), with the informal exception of
pints of beer (IIRC technically it's a "large" beer and 576ml). I
don't mind working in metric units, indeed I prefer them, but if
anyone wants to stop me asking for a pint in the pub they'll have a
fight on their hands!

Oh yes, cannabis is still sold by the fraction of an ounce as it ever
was, but I don't think selling cannabis in imperial units is any more
illegal than just selling cannabis

same in NZ - pounds and ounces for cannabis. Everybody uses imperial for
height still, and newborn babies are in pounds & ounces...
