El Jefé Azul™ (The Blue Chief)

A 30 to 50+ watt slice of pure tone heaven. El Jefé has the capability of utilizing several different power tube configurations and can easily be biased using the external bias controls on the amp's rear panel. Boasting complete point to point, hand wiring using the best materials, unrushed, right here in Austin, Texas U.S.A. We took our time on this one and it shows. This amp is a player's dream come true. Unlike other amplifiers, El Jefé has a sweetness throughout the volume range, and is very sensitive to the players touch. Possessing complex harmonics and sustain in the upper volume range, El Jefé cleans up nicely at lower volumes without losing articulation, warmth or personality. When paired with the ATL two-twelve Twin Cab™, El Jefé is a force to be reckoned with, possessing a dynamic sought after by many of the world's best players.

Exclusive and unique features of El Jefé Azul™ include the following:

1. Ability to use many different "octal" type power tubes with a simple bias adjustment. Note - output power is limited by tube dissipation.
2. External, user adjustable bias controls and test points. Complete operational instructions and current charts included.
3. Complexion™ control. An ATL exclusive - Complex harmonics are introduced and increased as the control is turned up, as well as raising power amp drive.
4. Custom wound Mercury Magnetics™ transformers.
5. Heavy gauge aircraft grade "sealed" aluminum chassis. ATL amps are completely RF shielded.

NOTE - Output wattage ratings are approximate and will vary according to the following:

1. Local source voltage (Line voltage at my bench in Austin averages 122 - 124 VAC. I consider this higher than average)
2. Tube brand / version (Output tube dissipation varies widely between brands and versions of tubes = not all 6V6's, 6L6's, EL34's or KT88's are created equal.)
3. Bias setting (Cooler bias settings usually yield lower output power, but remember - It's about tone, not power)
