Here's why I chose it:

The price was right! I've seen them on sale for £120+ and another Dual
505 on Ebay for 'spares or repairs' went for £60 just after I snagged
mine.

**The 505 was a disaster. You WILL be sorry. The 505-1 & 505-2 ,etc were
brilliant.

**OOps. Should read: "The 505-2 & 505-3, etc...."

There never was a 505-1. It was just the 505.


Whatever, it was the first of the 505s.

As you will realise, it has a headshell adapter fitted to accomodate the
Shure cartridge.

So, why was this model 'a disaster' ?


**The headshell falls apart IN EVERY SINGLE ONE. The headshells are NLA.

Send it back.

Which model of 505 did you buy?
Inflation aside, £77.00 isn't far off what a CS 505-1 cost when it
was
new.

Back in the day, the mags would have us believe a
Dual CS 505-1 turntable + New Acoustic Dimension 3020 integrated
amplifier + a pair of Acoustic Research AR19 loudspeakers
was the best buy budget system to own.

Ah, dreams of Rega Planar 3 and A&R Cambridge A60...

Getting a 'new' stylus for ancient cartridges can be a bit like being in a
shooting gallery blindfolded. Genuine 'new old stock' risks having
deteriorated. New 'third party' replacements may fit physically, but not be
like the originals in performance. Alas, much as I love my old Shure V15
I'm hesitant about modern replacement styli. So take care.

If you find the existing stylus or replacements aren't satisfactory, then
an alternative is someone like the 'Expert Stylus Company' who will
refurbish an old stylus.

You may be better off with the M55 than some other models, though as I
think that sort of level of Shure remained popular with 'DJs'. And probably
sold in bigger numbers than V15s.

I see people discussing fitting of CS505-3 or later headshells. (Not a
trivial task, apparently) But my understanding was that this was related
to cartridge compatibility and an alternative to the adapter kits. I
haven't seen any online info on the early ones actually falling apart.
If you could point me to such info on the mode of failure I would be
interested.

From the photos, the adapter on this CS505 does not look pretty and
must add some mass and therefore may affect performance. I'll take a
good look when it arrives.

Yup, prices of genuine 'New Old Stock' versus 'will fit M55E' items at
£12 a pop says something. I don't know what stylus is fitted to this one.

Of course there was a Dual CS 505-1.

Here's a link to an image of a genuine service manual cover: http://elektrotanya.com/PREVIEWS/634...05-1.pdf_1.png
Here's another link to further info: DUAL 505-1 Turntable
Here's a video clearly showing CS 505-1 on its model ID sticker and 505-1 on its serial number sticker: https://www.youtube.com/watch?v=zWOt5UNFKds

Here's a link to a 505/506-1 service information sheet dated 1980: http://elektrotanya.com/PREVIEWS/634..._sch.pdf_1.png

Here's a link to an image for a CS 505 instruction manual: http://dual.pytalhost.eu/505/cs505_1.jpg

Printing errors aside, it may not be that far-fetched to assume there are worldwide variations which include models: 505, CS 505, CS 505-1, CS 505-2, etc.
Whatever the accuracy of this assumption, it's an inescapable fact you couldn't walk down Tottenham Court Road without tripping over a CS 505-1.

Nonsense. I had one with near daily use for over 10 years, with and
without the 1/2" converter. Never missed a beat.

Can't speak for Antipodean imports :-)

Don't hold your breath :-)

It looks a little clumsy but works surprisingly well - and adds
considerable versatility, of course.

I like the Dual 505. A big thing for me is speed stability, and I found
the Dual good for a belt drive. The best I found was a Pink Triangle LPT
- which considering the Heath Robinson appearance I found amazing.

I use an old Technics 1200 at the moment - very pleased.

ABS is not UV stable. There is an alternative called PCABS which is
used instead.

**Thanks for that info. I thought ABS was quite stable.
