And that is the very core of this issue: economics. As a hobbyist, I'm only fixing up my own stuff and if it goes wrong again in a couple of years owing to the NOS parts I used having failed - I don't believe they will for a moment but simply for the sake of argument - then it's no big deal at all for me. It's a totally different story for professional repairers who would be foolish indeed to install anything other than good quality new parts from a reputable supplier. Sure it costs more, but for a pro, it's well worth it for all sorts of reasons. -- This message may be freely reproduced without limit or charge only via the Usenet protocol.

I've got a box full of the oil & paper caps that come in cubiod cans and they all tested fine (I have an awful lot of vintage spares here). Not so sure about the tubular paper caps which I assume you're talking about, though. -- This message may be freely reproduced without limit or charge only via the Usenet protocol.

Can you kindly provide a link to the supplier you refer to who's able to offer such truly extraordinary prices? |

Anchor Electronics, 2040 Walsh Avenue, Santa Clara, California 95050 USA http://www.anchor-electronics.com/ https://anchor-electronics.com/price-list.pdf Electrolytic capacitors are on page 13. I am a retail, over-the-counter customer. I do not know about their mail order policies, except the last page of the price list says "We Ship To USA & Canada Addresses Only." |

If they work right at power up and then fail, that really DOES sound like overheating. Yes, the thermal conductive stuff could dry out or lose good thermal contact. The springy hold down should be fairly easy to unhook, just play with it a bit. They should be able to be unhooked by hand, you should not need tools. Jon |

Before you attempt to remove anything, make sure that's where your problem is. If you can pin down the time it takes for the port to fail and it's repeatable, then keep the chip in question cool with some freeze spray (or canned duster turned upside down). You don't have to keep a frost on it just keep it from getting really hot. If the time before failure extends (or stops failing) with the chip in question cooler, then yes, you could be experiencing thermal failure. |
