One thing that's great about eBay is that many items that would otherwise end up in landfills find new homes.

Some old caps go for crazy prices:

Unfortunately these caps are almost certainly leaky and could damage the equipment, best to buy modern film caps for < $1 each.

About 7 years ago, the last servicer of RCA TV transmitters liquidated parts to include one lot of NOS .022uF Bumblebee caps - about 100 or so. It closed out at around 550 bucks, and the buyer then matched them by value and sold them in pairs - 140 dollars a pair. After 3 or 4 dozen sold, I was convinced of the gullibility of the audiophools, and the intelligence of the seller.....

At the time, it was mostly guitar amp rebuilders that were buying the old bumble bees. I sold a few lots for unbelievable money. There were articles going around saying how much better the amps sounded with old caps. Looks like some of them still believe it.

I've sold lots of old caps. If people want them, why not? I advertise them as used, untested and probably leaky. Several years ago I sold a few of the "audiophile" types I tested and measured which I sold with the appropriate caveats. No buyer complained.

One might say that audiophools have a large capacity for snake oil sales pitches. :mrgreen:

The bumble bees are saw after by electric guitar players, they swear that gives them a different sound. I repaired a guitar for a fried some time ago, replaced one of the caps, that was shorted, for a high quality cap and only got complaints. I had to buy on ebay a bumble bee, I think I paid $30 for a pair, and put it back on the guitar. I showed my fried that the "new" cap was leaky, but he said that the sound was very different. I could not hear the difference.
I willing to bet if I "made" a bumble bee with new components, he will not be able to tell the difference on the sound.

Hum... Someone is making a lot of money. Are those "new" caps enveloped on a brown plastic or are they being made using old technology. Either way that is a lot of money for .022uF of capacity.
Here is a little more information on this bees: https://luxe-radio.com/products/matched-pair-of-luxe-oil-filled-022mf-bumble-bee-capacitors-2

It's somewhat entertaining whenever I stumble upon a forum for musicians...

That forum reflects exactly the view of my friend. If there is a sound difference maybe by the different amount of leakage you get on the cap, that can probably be replicated by a modern cap and a resistor for a whole $0.87 in cost.
I don't know, that is what people believe.
One or two years ago we had a discussion in the repair section, from a guy that said that he would only use old caps when restoring a radio. We argued with him that it was likely that even old new stock will be leaky and likely to fail soon after installed. He said that if they have not been used they should be ok.

The old wax paper caps tend to leak more over time as the materials age. I don't know why those guys think they still sound the way they did 50-60 years ago!

I guess it falls in the category of a religious discussion; people are not easily dissuaded from their beliefs.

Wasn't there a thread a while ago where someone had posted a picture of one of the "new" bumblebees cut open to reveal a modern film cap inside?
