if I were willing to go through the bother of figuring out shipping and
all that kerfuffle, but I'd much rather avoid the trouble. I'm willing
to accept slightly below what it's worth, or rather roughly what it's
worth, but with free shipping (ie delivery, by myself, in a car!). The
sticking point is finding someone within 70 or 80 miles who'd be
interested.
I'm based in Sheffield but regularly travel to N.Wales, so anywhere
close to the relevant motorways counts as accessible. Likewise pretty
much anywhere in Yorkshire.

prized ZX81, running a homebrew RTTY/Morse translator! What a lovely
mixture of museum exhibits that would be, what a span of years; if I
could only find the relevant bits and have a go at resurrection :-)
Thanks for any input, sorry for the distracted ramblings ;¬)
Oh, and it's a Mark IV Avo.
If it's what we call a 'tube tester' over on this side of the pond, i.e.
a serviceman's that you stick a tube into and it tells you if the tube is
good, you may want to keep it around as a tool to keep the receiver alive.
I think it's a pretty fancy tool. Afaict it measures pretty much
everything of a valve's performance and allows you to set each voltage
appropriately for the various measurements.
The description given by one site is
"The AVO Mark 4 Valve Characteristic Meter comprises 19 valve holders.
input selector switch and variable operating parameters for testing
valves. Provision is made for by means of plug-in adaptors to cater for
newly introduced valve bases."
If you (or anyone else for that matter) are sufficiently curious, there
are some beautifully clear pics, from several angles, large and clear
enough to read the function of each control

Thanks for the reply anyhow, I suppose it's ebay or nothing. I'm not aware
of any antique-radio magazines in the UK or I'd consider advertising it
there. It's worth enough to make for a fractionally improved Christmas :-)
