They are out there folks, caveat emptor!
So I was browsing Mcintosh gear the other day when I came across a listing that startled me, and not because of the price. The person selling the gear advertised replacement coupling capacitors, then in the same breath says lytic replacement isn't necessary. I sent a message, see the picture:
This is just asking for a shorted power transformer in the future, I have a Mcintosh MX-110 with so much lytic induced hum I can't even listen to it. Now I understand that not all capacitors are bad, but in my book they are bad till replaced when it comes to vintage equipment. When you take into account the cost of some pieces of audio gear you'd think replacement just on the basis of safety would be the standard, but I guess not.
So pay attention who you buy from, and if they recommend against lytic replacement be very sceptical indeed. My own MC240 had caps so bad the rubber came out the bottoms of them, between the terminal posts.
