Besides, I've got this environmental consciousness -- dont' like to throw away things that's perfectly OK, for the sake of convenience.
Nor me.
In 30 years of buying hifi - every single component I have ever owned (including cables) has been sold to or given away to other people. (Even cartridges/styli) The last items I gave away were a Yamaha KX-580 cassette deck a few months ago (excellent,working and boxed) to my brother - because he still uses tapes - and a Denon tuner I got for a tenner from ebay. The last items I sold were a year old Arcam Solo-Mini for £500 and a three year old Nikon film scanner for £550.
At least in terms of hifi. my recycling 'credentials' have been impeccable.
With one exception - all those items were sold (or given away) in their original boxes too. (I put the £10 Denon tuner's box in the recycling bin.)
All of our old computers have either gone to friends or been donated to places like adult learning centres.
Same with all my cameras and lenses for the last 30 years too. Never thrown one away yet.
It helps to buy good stuff that lasts. Which brings me to your Rega. I have had Regas since 1983 (on and off) and never known one to suffer what you describe. A friend still uses one with the old Acos style (pre 1983) arm and his cable and connectors are fine.
Did you store it in an attic or garage?
