[Vintage-Audio] Re Gold Plated Audio Cables

[Duane Fischer, W8DBF]

Pete,

I learned about the switching power supply issue four or five years ago. I 
had to have some blown components in my MGA Super VHS deck replaced after a 
failure. Since the old blind dude rarely uses a remote, (I have an entire 
section of my six foot wood LD/CD storage unit full of about thirty of 
them!), I put a six outlet power strip with a reset capable circuit breaker 
and surge suppressor in line. So unless I am using the twin VHS decks, 
Yamaha LD player, Pioneer LD/DVD player, they remain powered totally down.

Pete is absolutely right. Doing what I did will extend the life of these 
expensive items for two to three times their normal always on life. Which 
can save you a lot of frustration, avoidable repair costs and expensive 
replacement units!

Since I do not trust these power strips surge protection, I also have a 
surge protection unit plugged into the wall outlet and the power strip 
plugged into it. It may be overkill, but better safe than surge sorry!

This is a really peculiar situation Peter, especially with the Sony CDRW 
deck. Too complicated to try and explain by e-mail. One of these days I will 
give you a landline and explain the entire scope of odd things that happen 
with modern technology.
