Sorry Dave, but this is on list. I recently bought a CD from Artekmedia and unfortunately it was broken in two in the post, obviously something heavy had snapped it. The offer to either send a new dis

I don't own a 7104. However there has been a lot of discussion here about them lately and while they are a marvelous work of art the CRT is delicate. In particular the micro Chanel wears out with use,

Sorry, all the ones I have are broken and would only make you grumpy. Don Black.

Is there enough room for it in the doghouse? Don Black.

A dollar? Don Black.

That would be a good feat since sadly Mr Adams has shuffled off this mortal coil. But he's probably right the first time, if you collect more it's like breaking the speed of light, that blue glow may

It's always good to remember the basics. If you don't have a second scope, measuring the circuit DC voltages will often point to the problem area. Don Black.

You got my point Craig. Murphy's law was a serious attempt to make us not overlook the slightest thing that might be wrong or it could be serious. The Challenger problem was also well known but not re

That and the Columbia were very sad events that shouldn't have happened. They were perfect examples of Murphy's law. Don Black.
