If they are making MP3s from vinyl they must have a computer to copy
the MP3s to a MP3 player.
It will have an audio input and sound recorder app.
So only need a codec to save the recorded input as an MP3. (which they
probably already have)

Not sure it's worth the effort to repair. You can get a USB turntable
for $35US plus shipping:

Back working with a silicone rubber flat belt, shame it is bright orange.
Looking under x30 the original band had a furrow along its centre. I've
since found a salvaged variant on this pinion , 2 angled cones with an
included angle of about 110 degrees but no ridge , just a rounded join
probably about .5mm diameter again. The band cannot deflect that much so
must ride on that central edge, like the one I just fixed. Perhaps bulbous
ones are just kinder on the rubber

Interesting. My 60" Mitsubishi DLP converts everything it receives,
whether OTA or from any HDMI or analog source, into 48 KHz stereo PCM for
its optical output. This allows me to use an ancient DAC with it and get
full functioning no matter what the source.

There may be a setup menu option for forcing the digital output of your TV
into PCM mode all of the time. Or not.

The MCM is spec'd at a 2.4GHz bandwidth, so it might provide better
performance in some systems. (I have no idea what the upper limits of cable
systems are.)

I'm using them with OTA digital TV which tops out at 700 MHz so it's
no problem at all. Our cable provider is currently topped out at
channel 135, under 900 MHz

Would anyone have a copy of the HP 210C Oscillator manual they could send
me, the one I found online was missing many pages.

Thanks

Dear Group Member

Just to advise that Grandata is still running and certainly has not
'Gone down the pan', We are still one of the largest component
suppliers in the Uk and have also added numerous other products to our
website.

Our old paper catalogue did list a lot of components which are still
not listed on the website, please always refer to the catalogue and
the website for components, should this fail then please email us and
we can try to find any special component that you may require and we
do our level best to help.

Kind Regards

Grandata

I have your paper 1999 catalogue in front of me. So are you telling me that
the ICs listed from page 10 to page 18 are still carried ( if not sold out
of course) but not found in stock if using your on-line search box. Whatever
IC (outside of power devices) I found in the paper listing was no longer
mentioned on the on-line cat .
