Nevermind the sound, the build quality and soldering is disgustingly shoddy. There are more bad solder joints than I care to count with blobs of solder all over the place, cold solder joints, and joints without enough solder. $50 DVD players have better solder joint quality than this piece of...

SinglePower Extreme, on the basis that the Woo 4 uses 12AU7 input tubes. 12AU7s were never designed for linearity and they can't be made to run linearly, they belong in guitar amps and have no place in hi-fi. Even a run of the mill 6SN7 such as the GE 6SN7GTA/B will handily outperform the best...

-113dB noise floor with a bandwidth of DC to over 100kHz? What a load of crock.

A transformer will break ground loops which reduces or eliminates hum & noise. Assuming the transformer is of decent quality, this will improve the sound.

Some tubes you can probably identify by their structure, a tube with "mouse ears" is almost certainly a Tung-Sol 6SN7. If you're lucky you should be able to recognize a few tubes this way. With VR tubes it should be pretty straightforward, put together a simple PSU and use an inline resistor...

Find a 60W lightbulb and the socket to go with it, they're readily available at any hardware store. Wire the speaker cables to the socket and adjust the volume until the lightbulb glows nicely. With the right music, you can even watch the bulbs flash in synch with the beat.

With a CD player, a hardware failure won't wipe out all your music.

Quote: Originally Posted by jamato8 Your concern is valid but in practice there aren't many designers who have followed this very closely, so Woo can't be faulted in a way. Cary Audio had 1000uf behind 2 GZ34's in their SLA50 and a good GZ34 would and does last for years in the circuit...

I'd like to direct your attention to the 5AR4 rectifier tube datasheet, which can be found here(PDF file). Note the maximum ratings, specifically the rating for maximum capacity with a condenser input filter. This number is 60uF. In other words, with a capacitor input filter, which is what the...

Depending on the sensitivity of the amplifier or preamp, active components can be omitted altogether. A simple step-up transformer connected to the output of the 1704 will perform I/V conversion and HF filtering all in one go. However, this is not the best idea if lengthy or highly capacitive...

I own one, or rather, I will until my daughter's birthday. I've owned & heard more amps than I care to remember and this is one of the very few standouts which I can actually recommend with a clear conscience. The 6S45, also known as the 6C45Pi is very similar to the Western Electric 437A, which...

Worst crisis in at least 50 years. That covers everything back to at least 1958. There is nothing between the end of the Great Depression and 1958 which was worse than the stagflation suffered during the 70's and early 80's. Meaning nothing, other than the Great Depression is worse than the...

When even the likes of Alan "Bubbles" Greenspan say that we're in the worst credit crisis in 50 years, it more or less means "crisis which may rival the Great Depression" when translated from Fed speak. Bloomberg article Excerpt: Quote: Former Federal Reserve Chairman Alan Greenspan...

I'm retired now. My degree is in Electrical Engineering and that's where I spent my entire career, focusing on instrumentation and RF design & prototyping. Audio was, and remains a way for me to unwind from the stresses of life, as a bonus I get to apply some of the things I learned from work to...
