Milbert Amplifiers

The Most Musical Amplifiers. Made in USA since 1986.

Think of It as a Spark Plug for your Autosound System

Vacuum tubes?! Why vacuum tubes?

Because tubes sound better!

Vacuum tubes, introduced near the turn of last century and often called electron valves, control the flow of electricity in a circuit and made electronics viable. They were used in all electronic equipment, even car radios, until smaller and cheaper transistors replaced them in the 1950's.

However, technological advancements are not always audible improvements: Many audiophiles, professional musicians and recording engineers still prefer the warm, musical sound of tubes to that of comparatively harsh, sterile transistors.

Until now, music lovers and car audio enthusiasts could only imagine true high fidelity in the automobile. Remaining crystal clear yet harshless and reproducing music that sounds at once natural, full-bodied, and life-like, Milbert Amplifiers mobile vacuum tube audio equipment makes that goal a reality.

Ok, so tube equipment sounds great, but what about reliability?

Patented circuitry operates the tubes properly so they last ten to fifteen years. Our circuitry is impervious to microphonics (noise from vibration). For example, dropping, kicking or even drop-kicking a BaM-235 car tube amp while it's playing will not damage it nor reveal even the slightest hint of noise.

Milbert Amplifiers mobile tube audio equipment is designed by ear to sound good and built for a lifetime of flawless operation. Each component is hand-made, thoroughly burned-in, and auditioned in the USA.

...but everyone says that.

Look and listen for yourself. You'll find many car audio companies that simply repackage the same old designs year after year or else diabolically redesign their gear cheaper to sell for less. As a result, car audio stagnates or converges towards an audible homogeneity:

" As technology marches on, it's getting harder to hear the smaller differences in sound quality between car audio components. " -Joel Cohen, Car Audio & Electronics, Jan.'92

That, over ten years ago. Our equipment thwarts Technology's incessant march towards homogenous sonic mediocrity and puts the fun back into driving.

Milbert Amplifiers, established 1986

Milbert Amplifiers began in 1986 with the idea that someone should do it right and make available top quality audio equipment for the car.

In 1986, our BaM-230 Owner's Manual noted that the BaM stored over 50 joules of energy, instantly available for peak musical demands. It wasn't until the mid 90's that someone else mentioned something about joules and energy storage. And, it wasn't until 2001 that we noticed another manufacturer proudly pander joules and energy storage in relation to their products, as if it were suddenly some grand new thing.

The BaM-230 mobile tube amplifier had the first "energy storage" capacitor of any consequence (50 joules), built in, designed in, in 1986 -- almost two decades ago. In fact, we store more energy inside the amp, directly on the output stages, than is available from four one-farad, 12volt capacitors (which would be on the far side of the power supply, anyway).

From 1986 -- over twenty years ago -- onward, we were
- including humongous energy storage at the output stages
- utilizing regulated, switching power supplies
- shipping heavy-duty mounting hardware
- including large, external fuseholders
- shipping 8gauge battery wire

Our products have always delivered
- vanishing negative feedback
- class A input stages
- overheat protection
- low-voltage shutoff protection
- reverse polarity protection
- fully regulated power

We build equipment to suit what we'd like to own ourselves. We're happy audiophiles appreciate these efforts.

But your ears reveal the truth that matters most; listen for yourself.
