Haven't been in for a while, but I'd like to report that yesterday I took delivery of a new guitar amplifier kit. Complete, with.... TUBES.

*must order more tubes rock shirts...*

Tubes Rock!

Tonight at the Brookdale Lodge, Brookdale, CA. Sunday in San Francisco at the Haight Ashbury Street Fair. Maybe Roger will wear his Tubes Rock T-shirt--how about it Rog?

Don't be surprised. Tubes handle much greater power levels than solid state circuitry.

I'm sure that the makers of multi-kilowatt power supplies shoehorned into tiny "bricks" suitable for mounting almost anywhere would be greatly surprised.

Tubes have a different transfer function than transistors, and as trans-conductance devices they operate differently from bipolar transistors (which are current amplifiers; FETs are closer to tubes in this respect).� However, the efficiency and power-handling characteristics of transistors is currently superior over a broad range of frequencies, voltages and power levels.� Face it, when the folks over at AC propulsion built the Tzero, they didn't build the motor drives with tubes.

...and Tau, FET's and MOSFET's are often used in guitar amps and effects (see Craig Anderton's Electronic Projects for Musicians--he gets a CMOS 4049 hex buffer--usually a digital chip--to distort like a tube amp) when tubes are too large, expensive, delicate, power-hungry or just plain heavy for the job. Otherwise, I guess people just prefer the sound of tubes....

My Vox Cambridge 30 amp has a single 12AX7 tube in the preamp for coloration, but an FET power amp. When I turn it up loud, it still doesn't sound or respond like an oversaturated tube starved for current, which is apparently very desireable, except to my neighbors :-)

Zorgon, enjoy your tube amp and turn it up to eleven!

Their latest note on price is "between Porsche and Ferrari."  Plus, it has neither heat nor real doors; it's a rich person's toy, not real transportation.  So unless I strike it rich somehow, I'm not going to get one either.  (Or maybe some rich person will buy one and get tired of it and sell it cheap...)

Yeah, but if I can't actually purchase one at any price, I can trick myself into believing that I *could* have it if it were available, rather than simply not being able to afford it anyway.

I like the sound of a Tube better but that is just me. I don't like the amps that don't use them.

Tubes still have niches where they're widely used: high-power radio transmitters, for one.

Well hey there all you solid staters.

I'm just a wee-bit disappointed in you.

Kurt Gibson limps up to the plate and hits the greatest home run in the history of baseball.

Kurt Warner goes from tossing wheaties at a Hy-Vee in Iowa to tossing touchdowns in the Super Bowl.

The American Soccer Team has the greatest World Cup in 70 years.

And were there any transistors in their footwear? NO!

They were all wearing -- TUBE-- socks. Tube Socks, 'cause tubes rock, I say.

So, Tubes Rock. And so do the people who wear them.
