Re: 100Wx5 Reciever nearly blowing out my 100W speakers?

You can't beat vintage for quality. I have several pair of Pioneer speakers from 1979 0r so. Woofers are 12" with cast aluminum baskets about a half inch thick. Damn things weigh about 60 lbs. each....

Re: Hooking up surround for 1970's stereo

If you care about music, you need two separate systems. Surround sound processors are not made for critical listening of music. I've had several different processors from several different companies...

Re: So I got an offer from a capacitor company...

Yum Yum indeed.

The lesson is transferable though. There are people that will sell you the garbage off the cutting room floor and still sleep good at night.

Re: So I got an offer from a capacitor company...

I was a poor college kid when I went to the grocery store. I found a cheap package of bacon. It had a little window to see one piece of bacon. Looked good to me and was half price compared to other...

Re: Anyone recognise these?

Shame is good, builds character!

When you can bend over in the middle of Wal-mart and puke your guts out and not feel shame, you've got enough character. Not until.

Re: Yamaha HTR-5920 cracked schottky diode

I've never owned a Yamaha, but I have read a lot of people griping about their crappy soldering. You probably flexed the board and made the bad solder worse. You could just reflow everything you can...

Re: class action lawsuit

Well you know how interconnected things are today with shell corp.'s and all. We could have been buying from Mattel toy company or Purina dog food and wouldn't know it.

Re: Intro - Need Suggestions!

I would suggest you buy gold, but my psychic sense says that's not what you meant. :)

Re: Mac Pro freezes daily!

Re: Mac Pro freezes daily!

Just about every computer I've had would get that way. It acts like it's lost part of a program and gets caught in a loop and can't go on until it finds that missing bit. I've always installed...

Re: Klipsch ProMedia 2.1 Amplifier is HOT!!! and bad smell in room

For the 5.1 it's been recommended for years to mount a fan blowing on those two resistors. I put one in mine back in 2007. It's had no problem since. A small fan and some zip ties. Others have gone...

Re: Reliability of BGA CPUs vs Socket

Yes they are. The second one I was populating, a tiny piece of the rubber got into the pin lock. When the pin needed to be removed later, the lock came out with the pin, not a good thing.

Re: Reliability of BGA CPUs vs Socket

Molex is a joke. Try working on a 40 pin Canon connector that costs $5000. I had a lock get stuck and came out with the pin. Things happen.
