Iām another with 40 odd yr old A5ā¦. Seems fine still although I have to look carefully for the white arrows now, a lot have faded over that time 
Hope thatās within the 5% relevancy factorā¦. 
I live in humid North Carolina and Iāve noticed my stranded copper speaker cables do oxidize over a period of about 5 years. I de-solder the terminations, cut off about 2-4" at the end and then re-solder the terminations back on. Canāt say Iāve noticed any remarkable improvement in the sound but it feels better to have nice clean connections.
I donāt think its A5 if itās 40 odd years old, maybe 30 odd? A5 replaced A4 in 1989 I believe.
It might sound better if you trim 5-10cm, being a European cable

Apologies, my typo! Is 30
If youāve had it for that long, youāre possibly a similar age to me - were allowed typos or fuzzy memories
Oh definitely!!
I occasionally polish cable terminators with Deoxit (other brands available) and it brings back the sparkle to any tarnished copper. Never tried it on the internal cabling of any component thoughā¦should be nicely tarnished inside the casesā¦
Is the correct answer.
The NACA4 on my Atom are from 1986.

Thanks. Inrigued now. The white label has a āDā on it.
I assumed it was an old Naim cable as it came with a seconhand Chrome Bumper NAXO/HICAP combination from the dealer when I got my SBLs (new) over 20 years ago.
I have literally never known Richard say that about anything hifi-related. It really must be an unknown.
Either that or heās been enjoying his birthday well enough for it to have affected his memory.

Well, at each birthday the memory fails a bit more.

ALmost 25 years ago tbh - I had no frame of reference and simply thought it was an older CB era interconnect as all my new stuff was olive - I had the option of new olive HICAP/SNAXO or pre-loved CB HICAP/NAXO and took the cheaper option as it simply sounded better āmore analogueā at the time when I almost exclusively had analogue sources.
Something of a curio then - maybe someone will recognise it!

From 2009, someone suggesting it was a from a CB too, have you asked before?
