Schiit Happened: The Story of the World's Most Improbable Start-Up

The caps in the above crossover from @corndog71 look like film (polyester mylar, polypropylene, polystyrene, pps) types and do not suffer from leakage, but some dielectric materials can be slightly hydroscopic and absorb moisture if stored in damp environment. The electrolytic type capacitor can dry out or leak electrolyte over time, generally exhibit higher leakage current and non-linearity vs the film types, but also typically offer higher capacitance and volumetric efficiency.

Re-capping not that difficult if one can solder. Polystyrenes have translucent casing & aluminum foil, typ found in smaller values only (use as bypasses) & on the surplus market, also more sensitive to overheating during soldering.

Some boutique film caps can get pricy though.

Danish speakers using dynaudio, scan-speak, vifa, or other hi-qual drivers worth recapping, esp if avail for a good price
Thanks @tincanear (with +1 from @LobalWarming ). Is it safe to assume the currents involved (using a Vidar) won't be a fire hazard... the wires are in direct contact with wood? I'm used to seeing such components on standoffs and/or circuit boards.

Question: do those capacitors suffer leakage (both physical and electrical) over time, and if they do, does it damage the circuit in any way? I'm only familiar with headphones (and the ones I have don't have caps an coils stuck to the headbands)!

There was a pair of Danish speakers on Canuck Audio Mart, with the seller saying that the crossovers had to be recapped (to get more performance out of them). It scared me away from making them my first pair of towers. Free advice, please. :)
No, these caps are film and foil caps. They are much more stable over a long period of time.
Film caps are also non-polarized which means there is no +/- .

The ones that leak or dry out are electrolytic caps. These are also polarized and connecting them the wrong way could destroy them. They look like this:

As long as they are not shorted at the crossover inputs you don’t have to worry about passive speaker crossover circuits with regards to current or voltage. The caps I often use may be rated 250-630 volts but they will never see those voltages in a speaker crossover.

We thought we knew Balsamic, until we were in Modena. We bought 5 different types after checking out a few makers and shops. Bliss. Problems arose later when we ordered directly - fancy bottles and packaging, but not the same. We will be there in September and we'll be picking up some more, perhaps a lot more. Looking forward to some Amarone and Barolo as well.

We will keep an eye out for Giusti as well!
LOVE good balsamic, but very hard to find here anymore. Amarone is Gerri’s favorite wine in the world, it’s my second favorite next to Brunello di Montalcino… Barolo is right up there as well, but even more expensive. Great reds one and all. Jealous of the trip!

@corndog71 (weird pseudonym, I love it). @bcowen ...I'm a sucker for labelled pictures of capacitors. Okay, so as long as I don't bridge the gaps with my tongue no issues (other than me emailing Schiit customer service and having them use decision trees from the OTHER binder). There's a Hi-Fi dealer in Ottawa that's willing to sell me a gently used pair of towers (100% green-lit CAM listing). :ksc75smile:

If the cap is fully discharged, not a big deal. Now trying to discharge a cap with your tongue? Yeah, probably something you only do once. 🤣

I'm better at solving problems unconsciously...! 🥱😴 🤪

Many problems can be created while blackout drunk. I've had a friend or 2 get in hot water and have no clue how they managed it.

** For the record, I've never been blackout drunk. I have the ability to know when enough is enough. After all, at a certain point you cannot have any more fun. And what's the point of having fun if one cannot remember it. 😂

Rookie. :slight_smile:
