Who Knows About Or Uses EFC-Wesco Mylar Film Caps???

Post by rp »

http://www.filmcapacitors.com/

I was reading on AudioKarma forum about restoring a Marantz 8B which someone here has and I might help him fix (if it's a simple enough job - at least I'll do no harm :)).

FYI VAC <http://www.vac-amps.com/> hired by Marantz Japan made a highly respected crazy ass faithful repo of the 8B amp in the mid 1990s, not a reissue but an incredible time warp simulation, finding the same paint supplier, having the meter and the E-Cans remade and painted, custom trannies, etc. Turns out for couplers they chose the Wescos, not sure which, as Goodall evolved into Wesco. From what I'm reading seems VAC still supplies parts for the originals and had these caps made (labeled) for them:

You never see these caps talked or used by guitar amp tone geeks. Nor supplied by suppliers to tone geeks. They seem a real alternative, at least big fun to experiment with. USA made? Are they just a re-brander of the same old caps?

Am I on to something? Anyone know? Anyone curious too?

Wesco even makes the crappy squashed ones if you need to restore a Sano :lol:

To save others some time the 1306TC film & foil, and 1313TC metalized look to be the interesting ones.

I emailed Wesco about finding a retailer w/ stock, and who'll do small orders. If you check the usual suspects and google you get an (odd) big dark hole. I'll see what they say.

Can't say I've seen Wesco's in anything, nor seen them offered for sale by any of the usual suspects, but I did see Good-all caps in all sorts of old gear from 1950-60's.

The white cylinder caps in that 8B look an awful lot like current Mallory 150, as you know one of my favorites. Some bumble bees in there too, bzzzzz bzzzz. Last 8B I saw, maybe 5 years ago, everything still original & working perfectly fine including tubes. Built to last. Sent it off with a clean bill of health to be sold at some absurdly high price.

Another rarely seen film cap, F-dyne. I have a couple but they're only 100V rated. Some of the hi fi crowd think they're the bees knees.

Looks to me too, but I have some '90s Dearborns that looks just like those and the 150s, reckon any axial film cap wrapped in white is going to look pretty much the same. Here's the word straight form a hifi poobah's mouth. Sure has me curious.

Now look at this, I just googled Dearborn out of curiosity and they have a wide range of not-the-usual-caps (unless they are just rebranding.) USA made?

So much choice just out of hand's reach...

Wish I had some entrepreneurial spirit and entrepreneurial money, I'd wholesale up a quantity of this stuff and and resell them to all you cap-sniffers out there. Not to mention getting a nice line of guitar amp e-caps made up from these guys:

Good ideas for someone with the resources to do it.

Anybody have experience with metalized polyphenylene sulfide.

I see some of the Dearborne caps use this as a film.

That should give the cap sniffers something to sniff. Mmmm, sulfide! :shock: Pee-yoo, smells like New Jersey. (Before anybody knocks me, hey I grew up there, I threw up there, I got out as soon as I could. Then it followed me here. :roll:)

It follows you to every corner of the earth. Wish they told us in 1945 that Newjerseyfication was the plan for the entire planet.

metalized polyphenylene sulfide sounds like a decongestant for a robot.

Some of theses caps are strange to see, it’s like a time warp catalog. If you search it borders on a googlewhack. I’m guessing the Wesco and Dearborn catalogs simply show what they can make if you send them a big enough order. Too bad for us cap-sniffers.

Whatever Vitamin Q is these days it can't be what GE killed the Hudson River with. Here you go fishies - it's Vitamin Q. (Not that I have any idea if PCBs was put in old caps.)

Hudson area residents have been warned for decades to severely limit eating fish, crabs etc. from the river. Zero for expecting mothers.

For years preceding the cleanup effort GE spent tens of millions $$$$$$$ putting ads on TV & radio trying to convince the public that cleaning up the river would result in decades of unsightly dredging etc. They also poured a lot of money into supporting public radio, NPR plus local stations, trying to wear their "good guy hat." And they bought off lots of local politicians who recited the GE line, cleaning up the river will be bad for business, blah blah blah. Now that the end of cleanup is in sight, turns out those sleazy pols have changed their minds. Hey, they got their cash, and GE cleaned up the river besides.

No doubt there's PCB & related items in old caps & transformers. They weren't old when they were made. It was the latest technology. "Better living thru chemistry."

Let's see what happens with the brownfield areas and polluted waterways in other areas. Keep an eye on North Adams Massachusetts for instance. Some of the old Sprague property has been turned to art facilities, that's nice but does it clean up the pollution? Sprague was the maker of Vitamin Q caps.

Also keep an ear on NPR. Whenever a big company puts their money into public radio it's often a pre-emptive move to get people to think better of them when they know they're about to be put through the wringer. Besides GE, Bank of America was a major NPR sponsor in the early 2000's. Stock investors can take NPR sponsorship as a tipoff from companies whose stock they should short-sell. wink wink wink ;)

rp, you should find a book "The Super Poison". It's about the Seveso incident near Milan on 10 July 1976. The town and highway got sprayed down with dioxin from a plant that was making hexachlorophene. All the company execs & politicians, trying to touch their ears with their shoulders & blame it on the other guy. Scary as any Stephen King novel, more so because it's real. Turns out there's no place that made hexachlorophene that didn't have an industrial accident. Including Clifton NJ, just a couple miles from where I grew up. I guess that's why we don't see the stuff anymore. In the 60's & early 70's it was being put in everything from surgical washup soap (Phisohex) to shampoo, toothpaste, & feminine hygiene products. Kills germs all right. Kills people too, when they make it.

Yep, I remember my sister washing her face twice everyday with Phisohex to treat her acne.

That stuff had an awful smell.
