Cautionary tale - Caig ProGold

Hi all, wanted to pass along a story from last week at the factory.

Over the years, I've heard Ralph caution customers (and others) against using contact dressing the likes of 'Caig ProGold' on tube sockets. I know the caution has appeared in the product manuals over time as well.

Last week, I had a particular troubleshooting case that wouldn't add up. Intermittent filaments, snap, crackle & pop, DC offset issues, etc. Running out of ideas, I asked the customer if they used any kind of contact 'enchancer' on the sockets.

Caig ProGold it was..! Customer spent a couple hours with cleaning swabs and 95% isopropyl removing roughly 4 years of residue. After this, the intermittent filament contact problems went away.

I'm not much for snake oil in general, nor do I really know what the intended use of this product is.. but, in short (or open as it were..;) best keep it out of your tube sockets.
