Couple Odd Brands

KDC, R&C, and KYS?

Images attached. The logo on KDC looks like something out of an 80's techno music video I would've seen on MTV. R&C sounds like some generic local lawyer's office name. KYS sounds like an angry 13 year old getting mad at some random person over the internet.

These are in a relatively old Logitech system that functions perfectly. Other than it claimed to be 120W and the IC inside can maybe do 50W on a good day.

The KDC was on the main amplifier board, while the R&C's were scattered everywhere used in what looks like signal processing. Then there's the KYS which all of them are on the power supply, nowhere else.

Anyone else seen these before?

Re: Couple Odd Brands

As I have lately seen some aduio equipment, replace crap on sight, as well as in anything else you want to run reliably for a long time. Just finished one bass speaker where all but three caps (two bipolar and one GP on the input which only sees 100Hz ripple from transformer) were bad, it basically ceased to work.

Than I got this something-cambridge-whatever Creative beast and not only the costruction quality is terrible, but the caps used are PoS. Most of the 100/200V caps are so terribly bad, one even corroded and fell of upon touching. And this crap cost like 500+ bucks new. This will be a long term project as - if the SMPS has not been killed by the caps rather than just being unable to work with them anymore - I have to most likely replace every single cap and clean huge amounts of chloroprene glue. The idiots basically used half a kilo of that and glued all the boards to the backside with like 3mm layer of that stuff. It is poured over the whole width of some of the boards where it of course already degraded and become conductive. You can guess what it does to audio equippment where only microamps of currents can ruing your day, interfering with the signal.

Re: Couple Odd Brands

Yeah your logo looks similar to mine (same font?).

I searched everything I could think of.

I think the logo is CA or CIA. The cap vent is in equal 3rds. Its a new power supply and the caps are okay, but I wanted to know if they are crap, as we've had problems with these power supplies in the past.

Re: Couple Odd Brands

CIA, that's crap for sure

Generaly if it's not proven good brand you can take it as a crap without doubts.

Checked the site, they don't seem to make electrolytic caps so I'm gonna say it's likely not them.

I got them to see what random brands i would get out of it.

And sometimes i get weird brands with funny names.

And sometimes i get familiar names like Cheng/ChengX Samxon, Capxon, GL[Gold Link if i remember correctly], Jamicon, and others.
