What is it about old tube radios?
There's something magic about them. Right?

Is it just a nostalgia thing or maybe an admiration of an era where class and elegance ruled! In these days of disposable technology, there are some things just worth saving.

Anybody still have a functioning tube set? How did you come by it?

And a big thanks to Octopart, our newest sponsor. Be sure to check 'em out!

That's It. Enjoy! 
Fix Up that Old Radio_

Even though they're ancient by today's standards, old tube radios can almost always be brought back to life, and there's still plenty of broadcasts out there for them to receive! Not to mention, they just look so classy and have a presence few modern electronics can match.

Clean Power

While clean power is frequently equated with green power, it can also refer to AC power free from spikes, dips, surges, audio, and RF noise. I recently learned the hard way that one of the precautions commonly taken to assure uninterrupted, clean power can take down your computer and potentially devastate your entire workshop.

Understanding Harmonics Using Simulation

Harmonics form a base line for testing, comparing, and explaining various circuits. This short tutorial shows how you can systematically look at the structure of complex circuits using a simulation program and building block approach.

I recently read a statement in a book that said switch contact bounce could "easily be eliminated by the fitting of a small capacitor" into the circuit. No details were given. Are you familiar with using a capacitor to eliminate bounce? If so, how do you determine the value of the capacitor, and how is it placed in relation to the switch?
